Bug when dragging files to other file group

I found a bug (pc win10x64) when draggng mastered files from 1 file group to another filegroup.
What happens, I save a wav file in file group 1 and after that, I drag it to file group2.
This works, but sometimes the file also stays in file group 1 and you can’t close it (nothing happens when you click the X), it stays there untill you close wavelab completely. I can close the file in file group 2, but stil the file stays open in file group 1 and I can’t close it.
I can close the complete file group 1 without problems and it’s in the audio files window.

Thanks for the report. I will have a look.

I have that happen too.

Until the bug is fixed, I have a workaround: I close the file. I go to the group I want it to appear in, and then re-open using ‘open recent audio files’.
