Trouble resurrecting uncredited credits for Mr. Magoo (1997)

I have trouble resurrecting uncredited credits for Mr. Magoo (1997) in contributions #250803-150924-929000 #250803-151459-788000 #250803-151659-355000 #250803-153835-639000 but IMDb rejected it. Here is the link where I've found them: https://web.archive.org/web/20250222211853/https://www.imdb.com/title/tt0119718/fullcredits/
