Unable to confirm cast list

Wish to confirm/verify cast list for Episode "The Truce" (1960) in "The Adventures of Robin Hood" https://www.imdb.com/title/tt0506430/reference/?ref_=fn_ttl_ttl_8 . Cast list on IMDb is marked "Complete, Cast awaiting verification". I've just photographed the cast list at the end of the episode (2 photos), and can confirm that the list is correct. But when attempting to edit with no change, I couldn't find the option to upload my photos as evidence so status can be changed to "verified". Can someone help please?
