Hi guys,
If you use the template/shortcode element to add the form to different pages, the form ID stays the same. If you copy the form manually (right click » copy) and paste it manually on the corresponding pages (right click » paste), it should actually work, because the form gets a new ID
Could it be that you have duplicated the template or the page that contains the form either with a “duplication” plugin, or saved it with a right-click » save as template?
If so, this is a bug we are already working on. The problem is described here using popup templates: WIP: Links & Inputs broken in popup, CSS overridden out of nowhere - #4 by mr.matt.eastwood
Best regards,
