Hi Jeannie,
Thanks for reaching out! I want to first confirm that we extended the deadline for your challenge account while we look into this — so all of your progress will be saved.
The different display names of ‘FAQ’ vs ‘FAQs’ shouldn’t be the issue because the filter is still targeting the same entity type.
We are looking into this though and will let you know once we figure out what the issue is here so you can complete this challenge!
