I also have the same problem. It is now day two of this. The mid rib has kinked and split from the leaf at the bottom right side.
My leafs have not yet came up like marenmars photo. My DC opens up like a cone. It seams like my bloodleaf stops growing straight up and half the leaf stops growing?
the other leaf I cut in half and then took another half of half =] bad wind damage the night it opened.
Edit: I went out after posting and decided to fix this. I pull gently unrolled as much lower leaf as I could and found the line where it was fixed to the new leaf and pulled apart.
I lost the lower inch and half off the right side of the new leaf but it will be fine. The new leaf was in their about 5-6" inches but looks good, was not kinked like I said earlier just bent.
If anyone cares to see I will take pics just let me know
