iPad Pro Logitech Combo Touch (Old Version) - Is this weird crease normal?

[ghsDUDE]

I got an amazing deal on an M2 iPad Pro and got the previous version of the Logitech Combo Touch (which is currently 50% off at Target).

Everything fits great, but I noticed this weird area on the crease in the back of the case.

Is this weird section in the middle of the crease normal? Wondering if anyone else can check theirs out and post a pic. Thanks!

I’ve owned three over the years and they all had it.
