Halo 2 anniversary coop not counting?

A buddy and I were running through the torture that is Halo 2 Legendary on co-op and after a few levels took a break. I looked back over my mission count and not one of them counted towards my completion but they did towards his. Is this a common bug? I’d really rather not have to do every level twice.

Did you have any 0.00x multiplier skulls active?

You have to be the host for it to count, I’ve had the same problem just now.

Are you sure you are looking at the Co-op record and not solo?

Nah, it just plain didn’t count. Seems borked.

Can confirm, we played co-op Halo 2 with a friend on Normal and only my progress registered on Waypoint. Her co-op campaign for Halo 2 is blank.
I was the host for all of the games. Looks like only host pushes his completing to Waypoint, the client does not.
