Cash Receipts/AR_OpenInvoice Issue

SOLVED

We are on Sage 100 Advanced ERP 2014 (v.5.10.1.0) and are running in to a semi-common issue in Cash Receipts Entry. I am not sure exactly how this happens but probably once a month we will attempt to receive payment for an invoice, but it will appear that the invoice is either partially or fully paid. I have tracked this down to a field in the AR_OpenInvoice table called PaymentsToday. This is the only field in all the AR tables that seems to show a "payment" for the invoice, changing the field to the correct amount through Data File Display and Maintenance fixes the issue but I am wondering why this keeps happening. We have a very experienced accounting team and I do not believe it is something they are doing but I suppose anything is possible.

Rebuilding the sort files, does NOT fix the issue.

Has anyone else seen this issue? Is rebuilding the key files the next logical step, and if so are there any concerns when rebuilding key files?

Any help is appreciated!
