What is wrong with this picture ?

[NZ_M3]

Could it be that it's upside down ?

I mean the upper pad to be installed down and the lower pad to be installed down ?
There is a difference between them and especially the lower one is 5mm thick.

Upper and lower rubber pad don't interchange - they are designed differently to stop that from happening in the first place (and yes I've tried before just to be sure).
