I fully admit that I’m new and perhaps the error is with me. 
I have ~250 albums I copied over. Some of them have 2 discs. I verified through Mp3tag that the “Album” is the same or both folders (ie: no longer has “XXX Disk 1” and “XXX Disk 2” - now just “XXX”). The discnumber is also correct (“1/2” and “2/2” as appropriate).
One of the disks doesn’t appear to be refreshing even when I choose “Refresh Metadata” for the album. The cover art doesn’t get updated and the Album title still shows “XXX Disk 2”.
I do have “prefer local metadata” checked BTW.
Thoughts?
