Vertical Configuration of Entity Types

Hello! I am working with a client who wants their services to show up in the vertical prompts, I noticed that only some of the Entity Type: Services were showing up. There is a linked service field in the vertical prompts which I think is triggering some of the searches but not others. For example: When I search “Speech Therapy Program” the vertical prompt does not show up. But a service like “Behavioral health” or “Audiology and Hearing Aid Center” appears in the vertical prompts.

Audiology and Hearing Aid Center:
