Changing a Customer Payment to a closed period.

SOLVED

We recently converted our Quickbooks to Sage. A couple customer payments that were paid in December 22 are reflected in January 23 and I need to change them to December 22. The problem is that Sage doesn’t let us save the change to Dec 22 because it’s not a valid period. This is frustrating and is throwing off our books as we’re trying to reconcile and clean up the accounts from the transfer. Is there any way around this? I personally hate that I can’t do anything in 2022 because Sage has decided this isn’t important….
