BUG: Action Button settings: Back doesn’t work in Hold and Double Tap menus

Device: GPSMAP H1, software 13.08, restarted the device multiple times.

Description:
In the Action Button settings, the option lists for Hold Action Button and Double Tap Action Button can’t be left with the BACK key or the on-screen < arrow. The only way out is to select an option, which changes the current assignment. In the Tap Action Button list, Back works as expected.

Steps to reproduce:

  1. Open Settings → Action Button.
  2. Select Hold Action Button (or Double Tap Action Button).
  3. Press BACK, or tap <.

Expected: return to the Action Button settings without changing anything.
Actual: nothing happens; you stay in the list until you select an option.
