This may be another one that can’t be resolved without some kind of manual override…
I have 2 albums “+ / -“ and a version “+ / - (Unmixed Masters Version)” and they don’t match. I assume it’s due to the weird title.
With this one I even tried forcing it by putting the versions in subfolders but that didn’t help either.
This isn’t a priority - it won’t affect many people I suspect, it’s my own solo album from 97 and I’m pretty sure I only sold about 9 copies and no one else in the world has the “Original Masters Version”
