Here is the one I was talking about that is probably same as yours. This was from Fairchild gardens years ago, but I've also grown it in Hawaii. It's a Namwah/Pisang Awak, but with some amount of persistent flowers below the bunch, and tapered fruit that don't fill out well. Could also be a similar, but different tissue culture off-type that has undergone the same basic mutation.
Honestly I would just get rid of it and replace with something else, was never a very productive plant, not as good as the other Namwahs.
