@Cynthia1244. Time to sit down with your PM and review your entire contract with them, including explaining how the cleaning fees are charged. Perhaps they have reduced the cleaning fee on Airbnb to appear more competitive, now that cleaning fees are included in the nightly tariff (a change made earlier this year). OR maybe they are double dipping. Either way its not a matter for Airbnb.
As you own the property you can appoint whomever you like and you should always be the host and then appoint your PM as a co host but you will be starting again with the reviews, etc.
Contact Airbnb to help you through the change if thats what you decide to do.
Good luck.
