Can someone please explain why my place can not be booked due to Covid-19

I saw several posts about others having this issue but I am still confused. Can no one book me? I had a small student group coming in from out of town to self isolate. How is that a problem for Airbnb? Message said they could not book due to Covid-19. I also thought it was because I was registered with open homes. I did not want to do that anymore because I read you can only get bookings from them even if it is for next year so basically closed for business. Instead I offered the place to the local hospital directly. I checked to make sure I was no longer with the program but I can not tell. When I click on it, button changes to green. I unclick. It is white. I check back and it is green again. Not sure if it automatically turns green if you go to that page or a glitch. Anyway, would be nice to know if anyone can book me at all.
