Trying to add Copyright Holder for Home Run on the Keys (1937) without success

I've tried now to add a Copyright Holder

MCMXXXVII The Vitaphone Corporation (on print)

for Home Run on the Keys (1937) https://www.imdb.com/title/tt0144970/, both times the submission declined, the message provided both times for the submission being declined being "unable to verify". With the latest submission 220628-200645-392000, I actually did provide the link to the IMDb page as the fourth image, that of the on screen title card, does contain this information (in my submission, I did have that "on print" in parentheses as that is what is on screen, I'm not sure if it is still the copyright holder). I'm not sure what else to do to have this information added.
