Unexpected merging while using <<group MergeLabels=Merge2>> in nested groups？

Hi, please see the screen capture for example.

In this case, I recommend using Merge1 instead of Merge2.
<<group MergeLabels Disablesubtotals>>
It will be slightly different, but you will get the correct grouping.
I will fix it.
