I'm sure this a a quickie

Its also something i've noticed when changing tag, but i never find a reliable way to repro.

For me the only way to solve this is to remove the title/titles, run library update, add the title/titles again and run library update

Having edited some more tags and re-run Library/Update on all four streamers, they are now all showing the anomalies.

So I am now following Tooka's methodology. And we'll see what this brings. 

In the meantime I need to go and cook a curry! 

Update: Having removed the two offending albums, three of the streamers updated correctly, the troublesome fourth is now showing:
   
However switching tfrom Library/Tag View to Library/Folder view enabled me to use Update This Folder at artist level; this removed the two albums from Library/Folder View, and has also cleared them from Library/Tag View.

Progress!!

I will now reinstate the albums and do a Library Update on all four streamers (having first checked on the curry).
