React VerticalResults don't highlighted markdown

II created a Custom Card component to be used on the VerticalResults component, I received the result, and inside the result, I can find the highlightedFields, like:

const highlightedFields = {
    highlightedFields: {
        name: {
            value: 'Request Medical Records and Documents',
            matchedSubstrings: [
                {
                    offset: 8,
                    length: 7,
                },
                {
                    offset: 16,
                    length: 7,
                },
            ],
        },
        c_webPageContent: {

A birth-verification contains the baby's name, date, time of birth, place of birth and parent's names. It is important that you keep this document for verification of birth until you receive the certified copy of your baby's birth certificate. To request an additional birth-verification letter, contact the Birth Certificate Office or the Health Information Management Department (Medical Records) at the medical center where your baby was born.\nBirth certificate office contact information \nBaptist\n504-391-5517\nInformation regarding your child's social security number\nIt typically takes two to four months to receive your child's Social Security number. If you need a Social Security number sooner, you may apply in person at any of the Social Security Administration's offices. You may also call the nationwide number at 800-772-1213 for additional information or visit the Social Security Number and Card page on the Social Security Administration's website.\nBirth registration & Louisiana paternity laws\nLouisiana laws govern the last name you are allowed to give your newborn child and the recording of the newborn child's father on the birth certificate. The laws differ depending upon whether the mother was married at the time of conception and birth. A current state or federally issued photo ID is required for mom and dad to be included on the child’s birth certificate.\nIf you are looking to establish paternity, please visit the Louisiana Paternity Establishment Program .\nQuestions regarding your child's birth certificate\nHow long does it take to receive the birth certificate?\nYou will receive a complimentary copy of your baby's birth certificate from the Louisiana Vital Records Office. It can take from three to six months to receive this copy.\nWhat do I do if there is a problem with the birth certificate?\nIf you need to make a correction on the birth certificate (i.e. incorrect date or time of birth, misspelled name, etc.), contact the hospital where your baby was born. Depending on the circumstances, the hospital may be able to issue a correction letter which you can submit to Vital Records to correct the birth certificate.\nIf you would like to make a change to the birth certificate (i.e. adding the father's name, changing the baby's name), contact Louisiana Vital Records at 504-219-4500 . There may be a fee to make these changes. For more information, please visit the State Registrar and Vital Records page of the Louisiana Department of Health website. \nStarting a personal health record\nAs a patient and healthcare consumer, you may have seen your chart at your doctor's office. In fact, you may have records at several doctors' offices. If you've ever been hospitalized, visited the emergency room or had surgery performed, you will have hospital records as well. Again, it is possible that you have records in more than one hospital. To keep track of all this information, it is a good idea to keep your own records in a personal health record. A personal health record is information about your health compiled and maintained by you. Individuals who are managing chronic disease conditions, such as diabetes, kidney disease or heart disease are strongly encouraged to create and maintain a personal health record.\nWhat kind of information would you put in a personal health record? You could start with the following:\nYour name, date of birth and emergency contact information\nYour blood type",
                matchedSubstrings: [],
            },
        },
    },
}

But the markdown content doesn’t have matchedSubstrings, but returns on the result because inside the content has match strings
