Airbnb professional critical bug with alteration requests and taxes

[Axel46]

We currently have the issue that when a guest requests an alteration that doesn't involve an actual price change, the system backs out the taxes and refunds them to the guest. This is a pretty critical issue since it affects revenue and tax collection, but, as is usual with all bugs reported to the help phone line, they are completely ignored. For example, when a guest submits an alteration adding or removing a guest that doesn't involve a nightly rate change, the system will refund the guest the taxes. 

We respectfully ask Airbnb to fix this problem as it pertains to revenue loss to the hosts.

Same exact issue here.  Been trying for four weeks to just get a response from Airbnb on this matter.  I see the taxes reduction with a price change as well.  Taxes are voided on any change made to a reservation.

I am having the same issue. Had AirBnb fixed this ?
