Movie Sets does not display correct artwork

Just love the new version!

I have each of the movies in the set as sub directories in the main directory for example \\MYMEDIASERVER\Videos\Harry Potter Complete 8-Film Collection\Harry Potter and the Chamber of Secrets (2002). I use MediaElck to manage my movie collection. Kodi displays the artwork for the first movie in the set instead of the artwork located in the main directory for the set. For example \\MYMEDIASERVER\Videos\Harry Potter Complete 8-Film Collection\folder.jpg

Thanks in advance for your help
