As others have stated, crestron logic symbols simply work.
Check all driving logic!
It's easy to get caught out if you are using the or to sum a bunch of pulsed signals and just one signal gets maintained hi. If you are expecting a pulse output from the or make sure all inputs go through a one shot of some sort, mos, wpulse etc.
If your driving signals are maintained and the or is not behaving as expected then you may need to re-think your logic.
