This is really weird, never had anything like it before…
I have an album - Clarence Penn - Dali in Cobble Hill (2012) which Plex refuses to identify correctly! It always comes up as Jesse Van Ruller - Dali in Cobble Hill (2012)! Yet, Jesse van Ruller is nowhere in the files/folder’s names or tags!? (however I do have lots of albums by JVR)
My embedded tags are correct and I’ve done the Plex Dance, Fix Match, Refresh Metadata AND renamed manually the artist under ‘Pencil’/General/Artist but it just reverts automatically back to ‘Jesse Van Ruller’
WTF is going on here!?? 
Thanks for the reply, it’s fixed!
You put me on the right track…
There’s this thing I do, which is to use the Artist tag field to put the artist I’m actually really interested in on that album.
I’m a guitarist and I usually use that Artist field to put the guitarist on that album. This way I can search Plex for that guitarist and find all the albums he’s played on.
Furthermore, I will often create a subfolder named FEATURING where I put all those albums where that guitarist appeared on.
So in this case, the album was sorted like: Audio/Adam Rogers/FEATURING/Clarence Penn - Dali in Cobble Hill (2012)
This works fine for dozens of other artists in my collection, don’t know why this one was so hard to fix but I finally just put it in the root of the Audio folder, Plex Danced, and put it back in its original location and now it’s fine…go figure 
For whatever technical reason, this one album got really badly messed up (and JVR wasn’t even the guitarist on that album!)
