Issues with the INVOLVEDPEOPLE tag and MusicBee

[Psy]

I've found something interesting regarding Musicbee tag system.

Just recently noticed that my statistics show that the most played artist is "producer", that, of course, I don't recognize as a band or artist name.
Searching for "producer" shows a bunch of random artists, but neither have any "producer" string in the tags shown by MusicBee.

Looking at the files using TagScanner, I've found that there is a tag named INVOLVEDPEOPLE that usually has this format:

INVOLVEDPEOPLE: producer:Aaron Dessner;keyboard and piano:Thomas Bartlett; etc

but many files only have this by default:

INVOLVEDPEOPLE: producer



Now, I used some library apps in the past, so that's probably a default behavior for some of them, but besides, since MusicBee can't edit or even show the content of this tag, and the tag can have a bunch of people and names, I think it is odd that the tag counts on the statistics.

What do you think?

Confirmed that after removing the "INVOLVEDPEOPLE: producer" tag from all the affected files, and only the ones that have the "producer" word alone, I no longer have "producer" as an artist on the statistics. Seems that MusicBee is expecting to have a yyy:xxx; formatted list on this tag, and gets confused if there is just a single word.
