change primary image

Hi, I have been trying to change the primary image of these three pages: https://www.imdb.com/title/tt3380722/?ref_=mv_close https://www.imdb.com/title/tt4601332/?ref_=ttep_ep_69 https://www.imdb.com/title/tt5702544/?ref_=tt_ov_ep_nx No matter what image I choose, I am unable to change the primary image. I understand the photos I wish to change to are not in portrait, but it should not be this hard to change an image. Can someone please help me resolve this?
