Hi,
Can you check for any Layout Element that sets “Full-width (no padding)” on its content tab?
I’ve checked the 2 pages and the first one seems to be affected by a Layout Element while the 2nd one isn’t.
The first one has its padding removed from “Full-width (no padding)” setting on a Layout Element while the 2nd one doesn’t, so it keeps the content padding added from the customizer. (Appearance > Customize > Layout > Containter “Content Padding” )
