It would be better if you did not disturb it again. The best thing (although I know this would be hard for you) might be to cut the leaves in half so the plant doesn;t have to support so much leaf material when rooting, but, at the same time, the water roots it has may step up and do the job...but its not an overnight thing. They have to make a sort of different kind of tissue. And one day is not a long time to see great results from potting up a cutting. Its basically in a sort of shock. It needs to get used to its new digs and figure out what it needs to do. And it will.
When you are trying to root plants like these vining aroids, think of it this way.
You are a Rhaphidophora tertasperma growing wild in the rainforest on a tree and you are quite happy. One day, poacher loggers come into your forest and decided to cut down your tree. In the process you get whacked into 1000 pieces and just left on top of the ground.
What are you going to do? Grow legs and walk over to the nearest pond, plop in the water, and root yourself?
No. You are going to lay there on top of the soil, get rained on, maybe animals are going to walk on you. But just by your nodes being in contact with the soil, eventually, you will re-root on your own. It may take time and you may look like hell for a while. But eventually you will pick up where you left off.
