how do i filter them out?
Well you press the filter button then hide composer only.
There’s plenty of docs in the wiki.
Thanks, i was able to filter them out of sight, but it appears the media count stays the same? Is there a way to just not have composers load into the artist field?
No they are needed to be able to filter and smart filter and everything related to composers.
A composer is an artist 
What do you mean by media count stays the same ?
Gotcha, i just assumed composers without an artist credit would only show up under composers. The way artists without a composer credit don’t show up under composers.
This number stays the same with composers filtered out of artists:
Hum yes small mistake, will be fixed.
