Help!

I bought this rooted monstera albo cutting over the summer. When I bought it, it had a mostly white baby leaf that never fully opened up, it just turned black and died so I chopped it.

I think it’s doing well because it has a new growth point and is pushing out aerial roots. The part I chopped is even sprouting a new leaf but it looks black on the end again. What should I do? Chop again? Let it go? I do plan on putting it on a moss pole.
