Images displaying third-party ownership or branding not deleted - Lancer

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 three photos of Lancer, such as this one: https://www.imdb.com/title/tt0062577/mediaviewer/rm1618509568/, 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 submission numbers: #250819-124843-521402 #250819-125040-483702 #250819-125055-520802 (admittedly, the branding isn't fully visible, but in the right corner below, one can clearly see the D of Decades along the part of the logo around the D) *all pictures had a watermark from tv channel Decades, which started in 2014, while Lancer is a 1960's series, a fact I pointed out in all contributions.
