Images displaying third-party ownership or branding not deleted

According to the image guide (https://help.imdb.com/article/contribution/images-videos/image-guidelines/G27LPBQZA7EAZGJW?ref_=helpms_helpart_inline#) "Images displaying third-party ownership or branding, such as watermarks." are not allowed.* For that reason, I tried to delete these photos: https://www.imdb.com/title/tt0065286/mediaviewer/rm712553473/ and https://www.imdb.com/title/tt0065286/mediaviewer/rm1622448385/ but my contributions were declined. Was this in error or does IMDb have a different idea of third-party ownership and/or branding than I do? These are the reference numbers: #250604-230133-006602 - #250604-225827-718002 - #250530-213330-662702 - #250530-213226-563702 * I know the guide also states that "Watermarks of the title's creators, such as the production company or TV channel, are acceptable", however that is not the case in my contributions. GetTV started airing in 2013, while the photos are for Dan August, an early 70's detective series, so GetTV is clearly not one of the title's creators.
