When re-importing track information, many tracks lose all thier tags in Engine 3.4.0.
I tried this after embedding album artwork to files to get around m4a artwork issue.
The files that still have tag information are a mix of mp3 & m4a files. I see no logic to the loss of data
I use apple music to manage my library.

To fix this issue, Im currently removing tracks and re-adding & Analysing, losing any saved cue points and loop information.
