AC/DC weird labeling situation

[HAPPY1]

Not sure if this is an wiim app issue but the app sees both AC/DC (2 albs) and AC (6 albs)

Ive deleted the tags off all albs and re-scanned with minimserver (which showed the albums as unknown artist. I added AC/DC tag to all albums but it went straight back to AC/DC and DC as artisits??

Anyone else had this issue?

Just to update the thread, the issue was with old ID tags. Updating to the latest version fixed the issue.
