I am willing to take a stab at this, so here goes...
1) If you say, "We have been having a problem," that would essentially mean that the problem has been continuing for a while and that a solution to the problem hasn't necessarily been found yet, as in:
"We have been having a problem with our heater since it first started snowing back in November. I don't know what to do about it. Do you think you could come take a look at it?"
2) If you say, "We are having a problem," that would essentially mean that a particular problem is happening again after having been resolved at least once in the past, as in:
"We are having the same problem with our heater that we had last week. Do you think you could come fix it again?"
3) If you say, "We have had a problem," (which is supposedly the actual quote), that would essentially mean that the problem has been solved, as in:
"We have had a problem with our heater in the past, but now it works perfectly well."
4) If you say, "We have a problem," that would essentially mean that there is a problem, the problem is urgent, and the problem probably won't go away any time soon, as in:
"We have a problem. It's -20C and snowing, and our heater is broken and no one can come repair it because the roads haven't been plowed yet."
I know I'm not giving you any grammar rules here, but I hope you can see the subtle differences between all four of your example sentences, at least in my point of view.

es ist ein bisschen kompliziert, aber es ist weil der Ausdruck ‚Houston we have a problem‘ einen Zustand erklärt. Es ist keine Aktivität.
Andererseits könnte man ‚Houston we’re having dinner‘ sagen, weil das eine Aktivität erklärt.
