I love EasyEDA Pro, but one thing I find SOO frustreating is how difficult it seems to be to clone a board. I've read the docs and the Clone command would be perfect, but it doesn't work on my system.

When I right click on a Board name and select Clone from the popup menu...

It doesn't clone the board and instead I get the following dialog instead.

I have no idea what it is trying to do?? What does it want me to Confrm? The docs about Clone do not show this dialog.

Often I stumble across a way forward using copy and Paste but today for some reason noting I try is successful to duplicate my Board. So I'm kinda stuck.

Does the Clone command actually work? How do others duplicate a Board within an existing project?
