Re-slapping CM button doesn't release flares

[scoobie]

Sorry for the strange title.

Tested in CE, but probably it's the same in EE and BE, too.
Settings as in the screenshot: "BOTH" and "PRGM".

Slap the release button - the program set on that fancy panel behind the seat gets started. So far so good.
Now, BEFORE the program completes, try "re-slapping" the button, numerous times if you like.
Each slap (the program is still running) will release chaff - cool, but WILL NOT release a flare - not cool.

In other words, for the time it takes to execute CM program, manual release of flares is disabled. Chaff work OK.

I may be doing something wrong (but what?) or otherwise that doesn't seem right. It may get you killed, I doubt the real device really worked like that. When I need another flare, I need it badly.

Since I knew something wasn't right, later I set a very specific program to test it easily - another screenshot. One chaff/flare, 8 seconds of delay, another chaff/flare.
