Original/Revised Contract Amount Discrepancy

With different frequency, but frequent enough to be a nuisance, especially when involving millions of dollars, the Original and Revised contract amounts get out of balance. Since it cannot be tracked easily, I'm wondering whether anyone has run into this as well. We're running Sage 100 2018  (6.0).

I correct it manually by using the Data File Utility, but would love to mitigate it if possible. Our Sage support group sent us this Sage document that deals with the manual correction, although this is for estimates and our issue is with contract amounts. When i pushed further about it, they said that it's just a bug.

Revised Estimate is incorrect in Job Masterfile Maintenance or in Job Cost reports.pdf
