A form's introduction was being repeated at the top of every page of a multi-page form, while the preview in the form builder showed it on the first page only. The builder was right: an introduction introduces the form, so it now appears once, at the start.
If you want wording partway through a form, the tools for that are a page title, which heads the page it belongs to, and a text block, which you can put anywhere among your questions. Both let you say something specific to that point in the form rather than repeating the opening.
Two smaller fixes came with it. The Next button now sits before Back, matching how buttons are ordered everywhere else on the site, with the main action first. And a form no longer jumps to the first question when it loads, which had been scrolling straight past the title and introduction.
