Kodi doesn’t display artworks scrapped from Ember

Hi guys, I’ve tried everything I could (I guess) to make artworks (Logo, ClearArt, Discart) scraped from Ember showing up within Kodi (Krypton) but nothing appears to work!

I guess the issue is not from Ember but from Kodi, any ideas how to get it working?

Knowing that movie scraped within Kodi displays the artworks properly by the way.
