Halo 2 Campaign

Why is it that every single time I try loading a Halo 2 mission on the remastered graphics, it automatically switches over to the old graphics? I’m also having problems with the time and score trackers not showing up.

I get the opposite I set the original classic mode and even though the option is set it reverts it to the remastered graphics. Then I have to pause the game and change it again.
