Problem connecting two outputs to LimitSpeed system output

JMandemaker

I'm trying to assign two different outputs to the LimitSpeed system output. According to the documentation I have, this should be possible. Robotstudio also lets me set it up that way. However when I then throw the switch that limits the speed only one of the ouputs gets set.

If I only assign either one signal it works fine. But when I try to assign two, only one works. Which one seems to depend on the order in which I created the system outputs. How can I get both signals to work simultaneously?

Our robot is running on robotware 6.02.1029.
