Placed Layer disappears when Exporting to PDF

[Brandon38564127p5zm]

I imported a PDF File into InDesign in order to turn it into a Form Fillable document. 

After I got all of the fields in place (Over 300 Text fields, 100 Radio Buttons, etc.) I tried to export it to an interactive PDF. When I do the background image on the first page disappears. The second page is just fine, but the first is completely gone.  Is there any way to fix this without completely redoing it?

It is not possible to place an interactive PDF in any form to get its interactivity upon PDF export alive.

I figured out the problem.

What I am doing is importing a Character Sheet from a TTRPG that I want to make fillable in PDF format. Which I have done successfully. I had a PDF of the sheet, and had placed it as a layer in InDesign that I was editing fields over. 

What had happened, was I had selected the field with the image and accidentally converted it into a text field which was overriding the image.
