Mma tracks not displaying artwork

[Cruelly3458]

I'm using MMA 2.0.5.1248. New issue where art for tracks isn't displaying. If I view by album all the art is there and likewise if I look at the track now playing, but no artwork displaying in playlists or if I select an album to view the tracks. I've put a couple of images to illustrate

I've tried rescanning the database but that didn't work so looking for other suggestions
