Images displaying third-party ownership or branding not deleted - The New Dick Van Dyke Show

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, on two occasions, to delete these photos from The New Dick Van Dyke Show: https://www.imdb.com/title/tt0066689/mediaviewer/rm3777289217/ https://www.imdb.com/title/tt0066689/mediaviewer/rm983096833/ https://www.imdb.com/title/tt0066689/mediaviewer/rm823580929/ 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 submissions numbers: #250717-221017-118602 #250717-221029-125302 #250717-221046-793802 #250729-190546-609602 #250729-190600-760002 #250729-190611-852302 *all pictures had a watermark from GoodLife TV Network, a network that started in 1985 while The New Dick Van Dyke Show is a 1970's show, a fact I pointed out in both contributions.
