I think there was a bug in Kodi with artwork that ends with a number, it will be fixed, but for now you could try changing the Kodi artwork settings, from Maximum to Custom, and then adding fanart1,fanart2,fanart3,fanart4... to the list of custom artwork.

Thanks! Tried this, but unfortunately this did not do the trick, either...

if you delete or change the one named fanart with a progressive number should work or is what happen to me. Important that noone have to be named fanart in the folder
