Radiobuttons in a HTML form to remain editable when exporting to PDF

Running into a problem when generating an editable PDF form a html form.

I have a html form with text input fields and radio button selections. When user submits, it will generate an editable PDF (with user-entered data) to the server.

I am able to get the text input fields to remain editable in the PDF but not the radio button selections. These radio buttons automatically rasterized to images.

Is there a solution to this problem? Thanks!
