#Known For Credits on company Home Page vs #Total Credits on Credits page

Does anyone know why on the Home Page of a company the number of "All Credits" is often massively different that the "Total Credits" on the Credits page? It seems these should be the same every time. But in many cases, I've found where the Known For # of credits might be 1241 while the total credits on the credits page is 70. This is not a one-off but for many companies. The Total Credits seems to be the accurate one based on the breakdown on that page, but where does this other number come from? EXAMPLE: John Wells Productions company: https://pro.imdb.com/company/co0037310/filmography/?ref_=co_ov_all_credits You see 914 known for credits, but 57 total credits on the credits page. Seems like they should be the same.
