ZeroScope X-Y mode “breaking” 3D plane when outputting both channels

I just received my ZeroScope today and I noticed that the X-Y scope seems to break the 3D plane when outputting both channels to my 1U Stereo Out/1U Headphone tiles.

I get the beautiful X-Y animations until plugging in my outputs and then it just turns into a 2D line. I’ve tried changing the time, compensation, and offset but I don’t see any differences.

I searched through the manual but I’m not sure if I’ve missed something explaining that this is normal or if I’ve run into an issue.

That should not happen. Please contact support@intellijel.com
