Grouping in reports DONE

Hi everyone!
I wonder if anyone noticed in their enviroment a rather unwanted and dangerous behavior of grouping in reports.
Today an acountant showed me, that when you apply grouping something really strange happens (ver. 2021.1.3.205). As seen on the attached screenshot the number of items in grouping is different than the one shown in the rectangle. This can be very misleading. And there is something even dangerous - in the ungrouped report I see some item that don't even show on the grouped one! I think grouping worked normally before the upgrade. Have you come accross such behaviour?
