Really no way for us to say what the bike "should" have. We can only help you with what is. It might have has a double/triple and a derailleur (mechanism) at one time, but there is nothing "incorrect" about a single front and 8-9 rear, and it has nothing to do with the crank arm problem. I agree we need some good pictures before we can advise further, as the way you are describing the problem is not clear.
