Having upgraded to 3.5, 4.0 and 4.1 in turn, and having installed the new check scanner external application, our accountant informs me that when using "Match Transactions" on a batch of scanned checks, it is no longer auto-filling in the appropriate people based on the account number. I verified that the bank numbers are still listed on the "contributions" profile tab, which the documentation indicates is all that's required.

What may have gotten lost in the upgrade(s) that might have caused this? The only thing in the release notes that I see is, "Fixed issue with transaction matching when masked account number was blank" (I'm not even sure what that means)
