Is this normal?

I bought my first ricordea a few weeks ago and since I've bought it I've had trouble finding a good spot for it in my tank. A few days after I bought it I noticed that part of it started sticking up. So I did some research and read that this may be because the ricordea isn't getting enough light. I put the ricordea really high up in my tank and it still hasn't changed. Any ideas why this is happening?
I have a 36 gal bow-front, with an innovative marine 24" 15w 1800 lumen light. My nitrite, nitrate, phosphate readings are all about 0 ppm.

Looks ok. They don't always sit flat.

Looks fine to me also. I have some in my personal tank that are towards the top and some on the sand bed and some look similar. You may notice that eventually it may split along one of the creases that it is creating.

Is there a known reason for why it decides to crease all of a sudden?
