Metadata not working / incomplete

Deleted my entire server. Relocated all my media to a new location on my drive.
Completely destroyed all cache files and started completely fresh using TheMovieDB Agent.
The ‘Plex Dance’ if you like. Scanned my media using the recommended settings (from a fresh install). At the moment, if you already have a movie cached as above (Hall Pass), it will always show the way it should, details are likely to have been pulled a while ago.

Add a completely new movie never seen by Plex before… you get this… (and is what I suppose a lot of new users are experiencing).

I’ve been using Plex perfectly for almost 7 years without a hitch. Until now.
