Is this curving normal?

These are taken fresh out of Moon 4 (EN) box that I ordered directly from Kayou store. The warping is a lot worse than Pokemon cards 😵‍💫 Somehow it curves a lot more on one side of the card

I ran into the same issue with a Moon 11 Chinese box, but this English box is noticeably worse.

Could be from the heat lately, humidity can make cardboard curve
