Old versions not showed on people´s versions page

I want to compile all the latest versions from a specific artist but the artist versions page do not show the oldest projects and it only shows a bunch of show and not more than 70 shots instead of hundred
I already tried clearing filters, unarchiving old projects.
if I go to the project versions page I can filter the artist’s versions and found them. artist is still added to old projects on artist info.
what it could be?

thanks!
