Customer due date same as invoice date

[lrousey]

We are on Macola ES 360 Version 4.0.0.323. Some of our OE customer due dates are showing the same as their invoice date, even if there terms are different (say Net30). It's very sporadic. One customer may have 10 invoices...the due date may be correct on 9 of them, but wrong on 1. It's happening on different customers.

Has anyone else seen this happening? If so, any suggestions on how to fix it?

Thanks for your help.
