Input/question data not being saved when continue pressed

I’m struggling with a continue button not working properly a few pages into a form.

I’ve noticed that if I have several blue containers that the continue only seems to go to the next page if placed in the following blue container, but my issue is that none of the form questions/data in the second blue section is being stored/remembered (it disappears on pressing the back button).

Has anyone had this issue before?
