Collection Eligibility Confirmed not popping

No matter what I do, I cannot get this achievement to come up and it’s still locked.

I’ve rapidly moved my mouse from left to right and picking up in very rapid succession.

I’ve tried slowly using the same method.

I’ve even tried a controller to get, which even got me farther than the mouse had previously and I saw Master Chief much faster!

No matter what I do, this achievement will NOT come up for me. Is it bugged?

Don’t worry; I checked my achievement list to make sure I didn’t have it. The end of POA also triggered anti-cheat in a solo run a while back (not any of these runs, though).
