Servo controller does not show up

[arystoteles]

Hello everyone
I am new to SketchyPhysics, I have made a simple cube and try to create a slider to rotate it.
Unfortunately when I create a slider (motor joint) and play the animation the slider does not show up.

When I open others sketchyphysics files form google warehouse I can see the sliders and they work normally.

What am I doing wrong?

I have included my file in attachement (SU 8, SketchyPhysics 3.1)
