I'm unable to reproduce this issue.

My steps:

  1. After homing the selector starts at position 5 (far right side).
  2. I select the left button until it reaches slot 1.
  3. Select right button to move the selector to slot 2
  4. Select middle button to start loading -- inspect idler at the same time
  5. Idler bearing is correctly moving to slot 2 such that the bearing is on top of the pulley gears.
