ATLS in Trainz 2022 issue


I have been testing and trying to solve this issue for days but there is no solution I could find. I have a normal intersection controlled by atls (2 road crossing and traffic lights). All seems fine when I make it the first time, traffic stops, slave works fine (slave trigger). When I save the session and come back, everything seems broken, traffic lights still work but the traffic stopper and the slave don't do anything. Is there anybody experiencing the same issue? Thank you!
