Hello
Please check now. I have inseterted your images in another row container and set the margin (0px 12%) - as you did for the other rows to keep them in center.
Previously the problem was - all other rows had only one column inside them and the margin was being applied to that column only. The three images were in three different columns and the margin was being applied to all of them hence the difference in rendering from other sections.
I have also set the background color of the outer row to #FFEEEF. And for lower screen resolutions to #fff to match the other rows.
Kindly check and Please do let me know if that works.
