This is an on-going issue that AirBnB refuses to resolve. It's an accounting nightmare and in my case looks like I, as a host, am skimming money from our listings. I too was told it was a "glitch" but later told this was their policy. There are at least three major accounting / tax issues that AirBnB has created if you manage multiple listings;
1. If a guest is credited any more for any reason after their stay, AirBnB debits that money from whatever the next schedules payout happens to be regardless of who owns the property of which bank account is associated with that property. So if a guest that stayed in "Property A" is given a $100 credit, that money could be debited to "Property B" or "Property C", etc. Until you run your revenue reports, you'll never even know.
2. If you manage a property in a municipality that does not automatically collect TOT and instead you set up your AirBnB account to add the TOT to the guest reservation, AirBnB will then strip out the TOT and deposit that portion of the funds in to your "default" account and the remainder in to the account you originally set up to receive it. In other words they deposit the rent in to the correct account and the TOT in to your separate default account. Yes, it creates an accounting nightmare!
3. Again, regardless of who get the money (in our case we are AirBnB set up to transfer funds to separate bank accounts based who owns the property), AirBnB sent me a 1099 for all funds from all properties, ignoring the fact that I never received most of the money. If that doesn't trigger some very big red flags with the IRS, I don't know what will. Imagine getting a 1099 for $100k when you only brought in $30k.
Of course I contacted AirBnb about these issues. Their customer service is atrocious! After working my way through the first two levels of pathetic customer service, a "manager" wrote this response below...
"You have 6 active listings on Airbnb and you have [correctly] set up routing rules for payout in 3 different accounts.
Please know Transient occupancy tax (TOT) and resolution center payouts (aka: refunds to guests) does not honor the specific routing rules, and can only be sent to the default payout method."
I also asked them, "Why would you make this a policy? It doesn't affect he guest at all and is nothing but bad for the host." No response.
Accounting nightmare!
