PDF Fillable form loses fillable fields after it is generated through Smartsheet

ahrenm1

We created a fillable form using Adobe Acrobat and use that as the mapping for our workflow automation to generate a document. We require a digital signature after the PDF is generated, but the digital signature option on the form does not copy over through the generating of the PDF. The formatting has copied over in the past, but it will not work now. Our agency cannot use DocuSign for this purpose. Any advice?
