This is our user guide on -How-to-Create-a-PDF-Form
If I am not mistaken, this is your jotform http://www.jotform.us/form/51255281705149 that you converted to Fillable PDF Form.
I checked the form and I noticed that it is indeed a very large form with multiple pages on it.
There are still some limitations to an extent the converted PDF form have. You can check for more details here
As of now, I can only suggest a re-design of your form to consider the limitations when being converted to PDF form.
Hope this help. Please let us know if there is more we can help you with.
