VC error

This used to work properly, but now my columns layout is wrong on mobile. I looked in the “responsive” settings on the visual composer module and things look right, so I’m not sure what’s going wrong. Will you assist?

The issue: On desktop, the food images are correct in 3 columns and 2 rows. On mobile, the columns are stacking vertically and are off center. Will you help me fix them by getting them into 2 columns of 3 rows?
