Primary Bank Reset

Since 24D we've had a number of calls come in from our users to say they are seeing the below error when trying to submit an expense:

"EXM-Document payee bank account number has an incorrect length. (EXM--1)
EXM-Document payee bank account number has an incorrect length.
Cause The message, EXM-Document payee bank account number has an incorrect length., can not be accessed.
Action Report this problem to an administrator."

Upon investigation, it appears that they have two bank accounts in expenses, an inactive and an active. The inactive is marked as primary, even though in some cases they've been inactive for years. The users state they have categorically not changed their bank accounts since adding the new one and it being made active and primary, they have raised expenses since and no issue. This has only happened post-24D.
