Cover art not showing on IMDB page

For my latest 2 films, i have uploaded the cover art / poster to both films TWICE

And both times it has not worked. I want the cover art to be the main picture on imdb for my films!Please can you advise how i do this in future so i dont have to resort to sending a message to fix!!!This one - https://www.imdb.com/title/tt37285492/

and this one - https://www.imdb.com/title/tt37285504/

You will see in the gallery for both films the last 2 images on both are the cover art

Please delete one and make one of them the main image on the page for both!!!!FYI - for both films when adding the image i chose these 2 "TYPES" - POSTER and PRODUCT/BOX ARTSurely one of them is correct.Can you fix both please.Thankyou
