Bend input cover normal?

Hi guys, I have a Framework 11th gen, which I upgraded to a 12th mainboard. I Always had a slight bend in the input cover and I would like to know, if thats normal. I was in batch 1 in germany, if that matters.
I added a picture, to show it. It isnt a huge bend, but it is visible while working on the machine, as there is the straight line of the display behind it.

Please reach out to support for assistance.

Thanks, I will do that.
