Length of a track not updated directly on the left screen when changing steps?

  1. Hold Trackpad to see Length of a track on the left screen
  2. Change tracklength from for example 16 steps to 32 steps with 2nd + right arrow
  3. The left screen will update Length to 32 steps, and the right screen shows duplication
  4. Use 2nd + left arrow to go back to 16 steps

Result: the Length will still show 32 steps until you press an arrow again or leave the menu

What you expert: Length of a track should be updated directly on the left screen when you move from bigger steps to smaller steps.

Or?
