Naval Abort Failure

[Vanman]

Allies wanting to Abort from Italian Coast after battle. Click abort. Abort Italian CA Trento to La Spezia works. Then when it is time to abort all Allied Naval/Air/Land unit to port it fails. Cannot transfer any units from the 'Units Currently Able to Move' box to the 'Units Chosen to Abort as a Group'. No combinations work, whether individual or by group. Take note that all Naval units are CW and all land units on Trans/Amph are USA. Also note that 'Current MP' is stated as USA, yet background is CW and switching Current MP to CW also does not work.
