Why headers and texts are only showing as gray boxes on fillable PDF form?

Hello guys, I have already added the option to display headers and text on submissions, i did a blank for without any conditions and its not from another template, i also did not use any widgets, just quick elements. When i first started my form header and text were displaying but then when i finished they did not display, it displays a grey background only on pdf format. 

Could you please tell me the fix for this, i have spent quite a bit of time trying to get this just right and nothing seems to work?

Apologies for the inconveniences this may have caused to you. 

I have tested your form and I can see the issue you're describing; however, I have tested the feature on a different form and it worked, I have also cloned your form and removed all the fields and noticed it worked as well, the issue seems to happen only when the fields are added to the form, all of them seem to be only basic fields so I'm not sure if this might be related to the number of fields and the text your form has, I'm forwarding this thread to our second level so our developers can further investigate the issue. 

We will let you know as soon as we get any update about it. 

We are sorry for this inconvenience. 

There might have been so many things which cause this problem. Mainly, if there is any injected CSS or if there is any field shrinked or if the form height does not fit the A4 paper size, the PDF form could have this problem. So, we strongly suggest you to clone your form to make following changes on your form in order to get a PDF without problem. 

1. Clone your form

2. Delete your css if you have injected any.

3. Unshrink field if you have already shrinked.

4. Add page break to your form to fit it to A4 paper size. If you have already page break, please try to change page break position. 

Please also note that when you add page break to your form or change position of them, there is still a possibility that the same problem will happen again. So, please try several times to get the best fit. Since, the code to download form as PDF seems have conflict if any of the above things exist.
