Missing thumbmails in second sql client

Hi,

Just set up my kodi 17 on 2 boxes. The second box does get movie/series info, but does not show all thumbnails, for example on the In Progress.

Some of my movies contain local .NFO (done by Ember in the past).

So all thumbnails are correct in the first install, that loads the SQL, in the second one it is fragmentated.
Any suggestions?
