Images displaying third-party ownership or branding not deleted - Owen Marshall, Counselor at Law

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 Owen Marshall, Counselor at Law, such as this one: https://www.imdb.com/title/tt0066696/mediaviewer/rm2845812481/ 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: #250708-001424-115602 #250708-001453-657402 #250708-001517-811602 #250708-001526-356702 #250708-001534-212402 #250708-001810-470302 #250708-001833-109802 #250708-001933-024302 #250708-001942-061002 #250708-001951-125902 #250708-002001-378402 #250708-002011-978602 #250708-002020-366802 #250708-002028-909702 #250708-002037-660102 #250708-002046-260702 #250708-002055-383102 #250708-002104-349502 #250708-002114-702202 #250708-002123-074802 #250708-002133-085002 #250708-002156-087602 #250708-002205-421002 #250708-002213-889502 #250708-002304-161302 *some pictures had a watermark from a Dailymotion user account (which I pointed out in every submission) while others had one of TV Land, a network that started in 1996 while Owen Marshall, Counselor at Law ran from 1971-1974.
