Cannot create symmetric pan effect.

[nt2ds]

Every time I try to create a symmetric Pan effect and then restart the shape it resets everything and behaves as a simple pan with no symmetric effect be even when recorded .
This happens on Titan Version 16 but couldn't get it working on 15.1 aswell.
Here is a video of what I am saying: https://www.youtube.com/watch?v=jz9R6a8DvUo
It works with everything else in the shape generator (such as dimmer effects)
Am I doing it wrong?

Either apply a 180 degree offset or reverse the direction but don't do both. For this effect doing both essentially cancels each other out giving the appearance of having no affect.
