Mortgage split issue following R46.12 update

:/ We often pay extra principal on our mortgage. Today, following the most recent update which took place this morning, I clicked on 'Split' to add in the extra payment, and the entire mortgage payment is showing on a blank line - principal, interest and escrow all showing zero.

This is the second time we've experienced issues following an update. The last time, historical paychecks were screwed up and we had to uninstall, then reinstall, pull in backup files, etc. Is this going to be a repeat performance?
