Reverse Columns Mobile

Please refer to the 2nd section of this website: Columns with numbers 1, 2, and 3 from left to right.

On mobile, the columns are reversed to display 3, 2, and 1.

html code looks like “reversecolumnsmobile” and I’m guessing that’s the issue but I don’t know how to change it. I’d like the 1 to display first on mobile as it displays left on desktop.

Thanks!
