Hello, I think I found the solution to this after airbnb being pretty much useless.
Go to your listings page (the page that shows all your listings), check the checkbox to the left of the listing you want to edit for the cleaning price. Then, at the bottom of the page should show "Edit listing selected". Select edit and go to "Fees and charges". Input your new cleaning fee and other prices you want to set and save. After refreshing my listing page it appeared at the price I wanted.
I had trouble with this same problem for the past week, but finally found that this works. Hope it helps!
