Primary image Hubert onhe Staller

Currently, this is the primary image for Hubert ohne Staller: https://www.imdb.com/title/tt2090883/mediaviewer/rm3811015425/ 

This is a poster for season ("Staffel" in German) 12. 

Can a staffer change it to this poster for season 1 please: https://www.imdb.com/title/tt2090883/mediaviewer/rm3163838976/ 

I tried via the regular route, but this particular picture can't be updated to become a primary image.
