Note the bulge on the stem.
That is a choke ...the new leaf gets clogged /stuck in the stem.
You now have unleashed it ...the leaf will continue to grow and straighten out.
This is the pic that I spoke to you about taken last night. I will do surgery later.
This is exactly what yours has done....If left alone the leaf will pop out the side.
Just clean up the rough edges.
You should be fine now
