Images displaying third-party ownership or branding not deleted - Our Miss Brooks #3

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 photos from Our Miss Brooks, such as this one: https://www.imdb.com/title/tt0044287/mediaviewer/rm2061048321/ 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: #250807-185335-238602 #250807-185345-420702 #250807-185354-462202 #250807-185402-804902 #250807-185411-147802 #250807-185426-974502 #250807-185435-585302 #250807-185446-669402 #250807-185454-935102 #250807-185504-571602 #250807-185515-764602 #250807-185526-946402 *all pictures had a watermark from Decades, a network that started in 2015 while Our Miss Brooks is a 1950's show, a fact I pointed out in each and every contribution. Even more important, this particular issue for this particular show has happened two times earlier already (see links below). Therefore, I'd like a message to be sent to the team dealing with this. https://community-imdb.sprinklr.com/conversations/data-issues-policy-discussions/images-displaying-thirdparty-ownership-or-branding-not-deleted-our-miss-brooks-2/688a5f79d885ee3d3954764f https://community-imdb.sprinklr.com/conversations/data-issues-policy-discussions/images-displaying-thirdparty-ownership-or-branding-not-deleted-our-miss-brooks/687cd6cd48216c184064137b
