Delete Images from an Old Title

Hi, 

I want to delete the images associated with a short film I directed years ago: 

https://www.imdb.com/title/tt9285100/?ref_=tt_mv_close

Images 1 - 3. These images aren't associated with my film and I have made repeat attempts to remove them. They are also of a very low quality and insinuate the film to be of low quality content also. 

Am I missing something as to why these images cannot be deleted? They literally have nothing to do with the project and is displaying incorrect information. Is this something that can be done with IMDb pro? 

Thanks so much,

Killian
