The curled leaves is the plant trying its best to protect itself from the intense heat and sun. Some shading will help greatly. Also check to insure that the tree is getting enough water.
I would baby them as Millet has suggested. If that does not work, you may have a slight graft incompatibility issue. From what I have read mandarins are typically compatible with sour orange, but there are exceptions.
Curled up leaves usually stay that way no matter what you do. That's my experience on many fruits. But those trees still produce nice fruit and big yields. My persimmon always curls. Same for my Goldrush apple. Both produce every year and a big yield of full sized fruit.
I didn't think of this earlier, but do you know if it is normal for this variety to have a cupped leaf? It is actually a characteristic of some citrus varieties to do that: Orlando Tangelo for example.

These are my first mandarin trees and in my preparation, I never read anything to suggest they were naturally cupping. Even so, some of this cupping does seem extreme. I'm inclined to trust Millet that it is weather stress.
Hi Travillion, here is a link I found that mentions folded leaves of the DaisySL Mandarin, with pictures of the foliage that show the leaves are somewhat folded. So, I wouldn't worry too much but it's a good idea that you moved it to a shady spot. Good luck!https://citrusvariety.ucr.edu/crc4203
