Left side of the keyboard is uneven.

Here's my keyboard on the left side, you can clearly see that keys around the "E" are almost sit flush to the palm rest piece.

And here's my right side of the keyboard for the comparison. It looks fine. and typing fine too.

Dell did change my keyboard bracket, keyboard and the palm rest piece but it's still the same.

Dell tech said that it doesn't affect any usage. and they will not change anything for me again.

For me, I don't think this look normal. And it's actually affected my usage a bit instead of hitting 100% at the key, I hit the palm rest piece and the key instead making the typing feel bad.

Do you think this is normal? What is the cause of it? and How to fix?

Thank you.
