Same here. I think I’m subconsciously learning to manage it so it doesn’t twist.
The belt naturally has a twist in it, just put it at the bottom and they function properly. It has to have a twist somewhere because it’s a flat object anchored to points at different angles. The belt should have one like half twist at the bottom, the belt will stay relatively flat everywhere else.
As long as your belt sits like this, it will track perfectly flat your your body when pulled over.
