Hi,
I do not see that anything disappears, when you proceed to the next page.
Data is saved in the answer table.
Everything is fine.
 



And that the radios are empty again when a respondent goes BACK to this question, well, who allows people to go back?

Okay, as said before, this is an old (an a bit unusual) script and it seems that the original thread isn't there anymore.
So you can't ask the author (as far as I remember he was Polish).
I can't help. Either you adapt it by yourself, wait for somebody here, or revise the layout.
You see, I am still wondering why you do not use built-in features like an array by column with some css ("no-question", "no-bottom") and inserted subheaders
 

Or something quite different (Sliders with or without tick marks)

And your second question (s324):
Something like GIGO (Garbage in - Garbage out).
It is obvious that you do not see anything, if there is no subquestion.
If you want to get a subquestion, but without header, you have to enter at least a blank.
