@Lola331 Service fees have nothing to do with your settings, aside from the option to have split host/guest fees or host-pays-all-fees. Airbnb determines its service fees.
Can you post a screenshot of what you are talking about? Charges can't be a negative amount.
P.S. 101 photos is way too many, plus there are many duplicate photos in your gallery. Edit it down to maybe 50 photos, max.
And your listing description is very scanty. You haven't really described the apartment at all.
