Halo Reach on Steam - LASO playlist time wrong

Hello,

I finally finished the last mission to get the “Why do you do this to yourself” achievement. I got the achievement and was really happy, since i spent almost 8 hours on it.

Thing is, when i checked to see how my time and score compares to the community i saw that my time and scoring stats are completely bugged.
It says that i spent 166 hours on the playlist and displays 0 score. But when i check in my career it tells me i spent 7 hours and 32 minutes in campaign.

Is there a way to fix that?

Greetings Psaimon
