↑↑↑When I use Upgrade planner on the underground belts with different colors and opposite directions, they became in the same direction.
I also tried the same operation in version 1.1.110, but they will not change to the same direction in version 1.1.110

I just tested this exact scenario and it all works fine. Do you have a save file with a small reproduction i could use to verify what steps i am missing?
