Do you mean that you ran the update tool to change from the split fee to the single fee @Deborah1238 ?
If so, you couldn't have changed back to the split fee structure (the system won't allow it). So I assume that you manually changed your calendar prices back to what they were before the change?
If that's the case, you will have to take them back up, because you're on the single fee now. If you don't you'll lose money as a host (and the guests will pay too little).
Check all your prices and make sure you put them back to where the tool had them: nightly rate, cleaning fee, pet fee, etc. (hopefully you remember which changes you made where).
