Bob, I’m going to go out on a limb here…………Cos your asking for help.
based on what I’ve read, but no practical experience with mutations. I would say it is just that. It’s a mutation.
i cant understand what benefit the breeder saw with joined leaf and stems, if it’s meant to be that way. Other that visual.
it could grow out on its own as leaf grows fairly quickly. But to me it doesn’t make sense.
it could be worthwhile to reach out to the breeder and see what they say. If nothing or no sensible response.
seeing as you have 2 plants the same. Maybe consider trying the following on one and leave the other to grow out.
I would get the scalpel. Slice the leaf on each side that is joining the branch stems together so the main cola can get light and grow. if left it may grow out on its own.
however, I would also be concerned that if I left it, it could get stifled and worse, eventually go moldy as moisture may get trapped in that funnel, if the joined leafs and stems don’t grow out.
I reckon the scalpel is your friend in this case. At least for one of them and if brave enough, both plants.
additionally, I don’t see any downside to cutting the leaf structure so the colas can be exposed.
