Type of Problem: Design_issue

Extra Details: There must be a problem in this series when uploading the posters, since I keep the proportion but it always gives me an error, I have even uploaded the poster by resizing it to 500x750 and it tells me that it does not meet the aspect ratio. Could you look at it? Thank you. Here I pass an imgur link of my poster uploaded to my account that should be taken by your website and you can see that it does not. "https://imgur.com/a/m9qmj0s"
