Don’t worry about it. They will correct themselves as they get bigger.
Mine did the exact same thing. I unrolled the leaf manually by hand once or twice, it ripped the leaf but I think it may have helped, you can try this or just leave it alone and see what happens. Here’s a picture of my trees this morning. My leafs were sticking together about two months ago but no problems since. Also, Get them in the ground if you can, they really take off once you do.
