Nostalgy shortcut voiding Undo command

Hi all. I have Nostalgy v3.2.17 running on Thunderbird Mac v78.13.0.

TB’s undo command is not working after I move an email from one folder to another using a Nostalgy keyboard shortcut.

If I manually drag an email to the folder, undo does work. But when I use the Nostalgy keyboard shortcut, the action does not even show up in the Edit menu, so undo has no effect. Any ideas? Thanks.

This is a known issue
