Credit not updating for title Gone Up North for a While (1972)

I have attempted to update the title to reflect that it was a TV movie for https://www.imdb.com/title/tt0225874/reference on 191109-025513-620000
however after multiple tries over several months, it doesn't seem to be updating.
I've included a reference to the government website stating it's status as a TV Movie, but still nothing. Is anyone able to assist?
Many thanks.
