Really Crazy Tracking problem with single Basestation

[forum.pimaxvr.com]

I want to use my Pimax 5k+ with a single Basestation, should work without problem as confirmed by many others.Now the funny part,I am in front of the Basestation where the X is marked, holding the Controller pointing at it.In the HMD i see the controller from the Basestation viewpoint !?The Controller Position tracking works, the Pimax HMD is like 3dof glued to the basestation viewpoint.Now you can say this is something Pimax need to fix and you could be right, but i just came here to ask if anyone have seen such Problem before and how this can happen.Any Idea?edit: check out this video i made...controllers are tracked proper but hmd is glued to basestatiom :(
