Or it could be that I’m not understanding. You are talking about the values under the “Panel Options” tab in each layout. When I add a new layout the values Top Spacing == Medium and Bottom Spacing == Medium are set. I also have no other groups set for the default template on pages.
If you have no other plugins but ACF and you’re and an unmodified version on Twenty Sixteen, I don’t know what could be different, so that’s a little confusing. I just tried it with 2016.
The only thing that I can think of is some kind of conflict with another field on the page. Are there any other field groups are used on the same location?
