Getting issues in motion study with 5 path mate motor.

Hello Everyone,

Hope you are safe in this pandemic situation.

I am making a movable Belt conveyor as shown in below image.
i am getting issues in motion study, i applied the 5 motor separately with path mate (Part Name Strip) in motion analysis.
after that when i did the Calculation process, 2 or 3 strips of part has been hide from screen. or sometimes getting flipped by path.

Other Data;
Belt length : 23000 mm
motor speed: 300 mm/Sec

any one know what is the problem in this and how to solve it ?

and after getting solution, I want to make the all three conveyor movable in as shown in Image "Full Assembly"

one more thing, How to remove/Hide that Red,Blue and Green colored Arrow shown in some images.

Thank you !
