Tracking Issue with Index Controllers, but not Vive wands.

Essentially I bought an original Vive way back when it came out and a while ago I got some Index Controllers which are amazing. Fast Forward I am now using a Valve index headset as well, however I am having some very strange tracking issues with the controllers...

In a certain area of my tracking space I appear to have a dead space where if my controllers are in they shoot of into space. Seems simple enough, however I don't have the issues with the original Vive wands. So I'm at a bit of a loss, I tried rerunning the room set up several times but that doesn't seem to help. I also don't have any reflective surfaces that should be effecting the tracking that I'm aware of.

Does anyone have any ideas?
