This is a known problem for Hosts with Rooms. Airbnb seems to think ALL listings with Rooms should show the bedroom photo first. To correct this and choose your own photo as the Cover photo guests will see, you have to delete the bedroom photo. Then choose which photo you want as the cover photo. Then add the bedroom photo back to the listing.
Be advise their AI bots will periodically go back and change it back to the bedroom photo again, so you will have to keep checking using incognito mode in a browswer as a guest to double check and will have to change it again.
