Based on your frequent contributions to this forum, @dalacor, I assume you update your software regularly. I don’t know exactly when the change was made, but I noticed it on August 7th of this year and created a topic for it: Custom view template does not show amounts credited - #10 by lubos
The problem I first noticed was failure of custom view templates to show amounts credited for a customer. But overdue, paid in full, and such “stamps” were all affected.
