Problem copying between documents

[Doc_Pit]

I’m trying to copy a group from one Photoshop document to another.  Usually, I either drag the group into the other open document or R-click and choose “duplicate.”  What’s happening now is that, while the group duplicates, it’s empty.  None of the subfolders or their layers have transferred.  It’s not a case of their being hidden.  The folder is just empty.  Any idea what the cause might be?

There was recent bug in photoshop 2020 in that regard which is said to have neen fixed in the very lastest version 21.2.2.

In photoshop under Help>System Info what photoshop version is listed?
