I'm trying to get fields to show in a single column on the page, as well as the field groups (there are three) they are in. Each field group has "Single Column" enabled. Each field has "Column Break" enabled. This works as expected in a number of accounts. However, I've just run into an account where the field groups are showing side by side. Any idea why one account shows the page differently? Is there an account somewhere that might have an impact?
