The issue I had, the "yellow" banana pistols (for lack of a better word) pollinated my plants. Not many, but the plant itself self-seeded as did two neighbors. Only a few seeds, but nice ones.
The seeds I got were inside the lower buds. If a plant is making seeds, it's at the end of it's life cycle. I am not sure that you can turn a plant around that is seeding, but looks like you are giving it a good try. If the cutting was from a morph, and is also displaying as a morph, if you manage to save it, it will most likely morph again when you try to bud it again.
Unless you want some seed, I wouldn't keep it.
