I stumbled on this thread today, but turned out to have different problem. I was going for a CCIP drop and couldn't get the bomb active. Turned out I had to enter a laser code to activate it. I'm guessing this is a bug as there is no point in entering a code in this case and it doesn't matter what I enter. I'll leave this here in case someone runs into the same problem (e.g. mission 1 of Operation Pontus).
