I somehow don't understand what the "Album Version" tag should describe, neither can i put something into the field. It's there because i applied it with Ctrl + D but it's not visible.
Is this supposed to be:
- Limited edition
- Special Edition
- Digibook Edition ....
Yes, it is intended to be used to describe releases just as you mention it.
We have been able to reproduce the apply issue and will correct it.
