tagCustom + Raumfeld

[spiky127]

I am using Raumfeld as a streamer with the respective Raumfeld app and have minimserver running on a Synology NAS. For my Linn setup (MDSM+Kinsky) it works fine.
With the Raumfeld app I have issues when I go the album view, it groups the albums according to the composer of a song, which of course can be multiple per album. So my albums are split per composer.
My guess is, it has to do with the "tagCustom" entry which shows "Composer.displayRole={artist, author}" but I have no idea how to change it.
I also don't want my Linn set up negatively impacted by a change.

Thanks for the help.
