Had something similar on my Sauk Dr.'s. I suppose I can expect something like that on the thicker leather of the Sauk, and I was OK with it, since I figure they would wrinkle and crease over time anyway. I did use some AE leather lotion on them, and it helped a little.
Picture is right after unboxing. Don't have a fresh picture just now.
Your Sauk Drives are a completely different leather. They are a Dublin leather which will crackle/wrinkle/pull up in areas where it creases. It is a nature of the leather.
