File Tags shown in the "Performed by" section

[Rainer_Muller (Rainer)]

I’ve asked this question before, but the rules seem to have changed in the last build:

I want to see the soloist of a concerto in the “performed by” section near the Tracks.
In previous builds this could be achieved with the file tag:
PERSONNEL Maurizio Pollini - Soloist

This does not work anymore, it seems. From the “roles” belonging to the Personnel tag, only a few seem to be shown in the “performed by” section: Orchestra, Ensemble, Group.

So my tagging strategy collapsed. Any ideas, maybe by @joel?

… ah, well … this could be a problem related to my tagging software.

No worries.
