[Poweramp showing two artists even though there is only one?]

Some of my tracks are showing a second artist even though Meta data on 19/20 other players apps is not showing the 2nd artist anywhere.

I did look with mp3tag and it does show a 2nd artist tag which I didn't even know was a thing but every other music player and app is not showing this.

I used a few only meta data tools and a couple show the 2nd artist but most don't

Is there a way to disable this instead of cleaning up all these tags?

What is Poweramp doing differently than all the other music players including itunes?

 

 

[How is artist label handled with different casing?]

I have some music labeled from the band OneRepublic labeled as OneRepublic and some tracks as Onerepublic Poweramp is displaying everything as Onerepublic even though the meta data is different. Is this intentional?

[Full queue of what's next?]

When I do shuffle all, I can see the next song coming up but is there anyway to see an expanded list? 

[Full rescan occurring often?]

Thanks! What triggers an auto scan? A reboot? 

[Full rescan occurring often?]

[Full rescan occurring often?]

Almost every so often I notice my files don't look right and a full scan is occurring. 

This only started happening recently any idea if this is normal?

It seems to always happen after a reboot.
