reported CMS gets stuck in prog Z if cms left or short long is used twice

[Puma]

Set any cms program.

cmsp in manual.

start 6 flare and observe the program display Z (correct).

before the 6 flares finish, start 6 chaff.

Wait for the program to finish and observe that the program remains on Z (bug).  Can be cycled back but takes clicking through the whole alphabet.

 

Expected behaviour: after any quick-program Z, the original non-Z program should be restored.
