Calibre 6.21 and still a problem.

I've edited the eBook. Saved the eBook and closed the editor. Deleted the original_epub file. Went to the metadata editor and edited the metadata. And I'm still getting an error. This eBooks was not open in another program.

Can we please say this isn't working and back it off?

calibre, version 6.21.0
