Hi KODser, your Tip was pretty good to disable the Media Icons, I didn't think of that. You were right, actually the First Episode with the missing Icon is VC1 and the others are WVC1.
I found the Fix which actually was pretty easy, it's because of the Hyphen in the Filename of media/flags/source/vc-1. Renaming it to vc1 solved it and makes the Icon visible. It may have changed internally in Kodi I believe.

I would keep the vc-1.png and duplicate it and rename it vc1.png. maybe there are encoders that put the tag vc1 on the files and others that put vc-1, don't know. Glad that the problem is solved

Good Idea, done that, thanks ;-)
