Symmetrical Layout

[BlubbelFasel]

I began planning my layout for my supermarket and didn't understand why the space between my right shelves were smaller than the space between my left shelves even though I put them both according to the grid. I later realized that the grid/ supermarket layout isn't symmetrical.
The grid for the supermarket on the right starts behind the walls for the warehouse as for the grid on the left it starts directly from the walls. That means the space on the right is smaller than the left space between each pillar.

I didn't notice it befofe but now that I did it's bugging me 😂🥲
Did anyone else notice it? Do you think it would be possible to correct it in the future?
