I'm having he same issue with the T16. It seems that it gets stuck near the sides of the MFD and will not move again. If the display select button is pressed, the curser remains stuck in the center point.
I tried to record the issue while learning how to use the TSD so please excuse Wag's video in the background

Adding a small Null in the axis seems to be working for me at tis point
