We just updated from PB12.5.2 to 2019R2, and noticed an issue filtering one of our reports.

The report is a composite DataWindow, grouped, with nested report objects in the group header bands. It displays properly on the initial retrieve, but nested reports disappear after a Filter() is a applied. 

Using external DataWindows with embedded data works fine, but nested reports disappear when the child objects have queries.

This was working without issue in the previous version, so does anyone know a workaround or if this was resolved with a patch?

I attached an example showing the issue. The DWs have Oracle "DUAL" queries behind them, but they can be easily updated to pull dummy data from any database.
