Movie Cover Art Not Showing

I recently purchased a 75 Inch Samsung Smart TV. I installed Serviio so we could watch the movies that are stored on my PC on the TV. For the first few days all the movies had their own cover art but for some reason they have all disappeared. We now have the same film strip and camera picture for all movies. Does anyone know how to get the cover art to display again?
Thanks in advanced

Looks like the F series don't support it (possibly got broken with a firmware update)

I wonder if it will be fixed in a new update then. I had them there for a couple of days but now vanished.

Thanks for your reply
