Headbet on the sides flatter than in the middle

Dear Prusa-community,

I have the following issue with my MK3S+: My heated bed is uneven. It is flatter on the sides (left and right) than in the middle, meaning there is a curvature towards the center. This causes smaller prints to adhere well in the middle but not at the edges. Could this be due to the spacers between the heated bed and the Y-carriage? In the middle of the heated bed, there is a spacer with a screw, and on the other 8 screws at the edges, there is a nut. I have the feeling that this central spacer is higher than the nuts at the edges - which, of course, would result in the middle being higher than the edges. Are there ways to correct this? For example, adding washers under the spacer nuts at the edges? Or not tightening the edges as firmly?

Thank you for your support!

P.S. This is my first post in a forum - please forgive me if I'm not doing everything correctly!
