BB Manager - Missing Effect to Song mapping info

See the attached error message…
All I wanted to do is export “Brushes 5” from the Brushes Beats folder, then re-import it into my own setlist folder.
I tried the process a couple of times, exported, then tried to import again - no success.
It does work with other beats from the same folder though.

Any suggestions how to fix this?

TLDR:
Before exporting a song, rename the song name so it doesn’t have any symbols that are prohibited by the file system.
The list of the prohibited symbols is as follows \ / : * ? " < > |
That way you won’t have errors on importing a song.
