Continue forms latter doesn't work for me

I use a lightbox and fill in the data with iframeParameters. But this does not work well for me with "Continue forms latter - Enaeble". My data is being overwritten. How to make my data priority.

I see that you have the same question following this thread: https://www.jotform.com/answers/1119328 

To prevent confusion over the the case of multiplicity, we'll give our response on the other thread instead.

Thanks for your understanding.
