Why are columns on the product page inverting?

Hi! I’m working on the code and created duplicate documents, just modifying the names to be able to use them in Theme Templates.
I created Template, Section, and Snippet, where the Template calls Section, and this one calls Snippet (is it correct?).
I don’t know why, on the products page, the left column and the right column (divs → product-single__meta, grid_item) end up inverting since I didn’t change the code.
The documents I created are the same as the originals.
Is this the order of calling the documents, or is there some other document I should work on it?
What’s the mystery that I can’t see?

Thanks!
