Halo 3 Forge keybinds reset all Halo 3 controls.

I have already deleted my game settings file a week ago to try and solve this issue, but it seems to be persistent.
Everytime I rebind the Halo 3 Forge controls to something I’m more comfortable with, they stick. However, once I close the game and play it again later, all of my Halo 3 keybinds that I have set will reset to default, not just the Forge ones.
