Spacing ... upfront

I have reduced the spacing at the bottom between the 2 sections from 90px to 50px...right above workshop section. I have also reduced spacing between workshop heading and its content. It appears perfectly within upfront but when I save and exit, it is showing the 90px padding and space after workshop heading.

I have cleared browser cache. I have even tried a different browser but just can't seem to to get to appear correctly.
