Hello ​@REH 
Thank you for reaching out, and welcome to the Docusign Community! We appreciate your question and assure you that we are fully committed to providing you with the best service possible. 
Docusign relies on the PDF's underlying structure. If the PDF's fillable fields were not created or saved properly, Docusign may be unable to convert them into Docusign fields. 

What you should do as a solution is as follows.

1. Fill the PDF with Adobe Acrobat/Reader:

• Open the PDF in Adobe Acrobat or Reader and fill out the fields using Adobe's tools. 
• Print to a new PDF: After filling the form in Adobe, "Print" it to a new PDF file to resolve the issue. 
• Upload the saved PDF: Upload this newly created PDF to Docusign. 

2. Use Docusign's Tools:

• Upload the blank PDF: Upload the PDF to a Docusign envelope. 
• Add fields with Docusign: Drag and drop the required Docusign fields onto the document to ensure they are properly recognized and formatted. 

Instead of pre-filling the PDF, you can:

3. Check PDF Settings:

Make sure the original PDF is a true fillable form. Some forms are created as "images" or "non-interactive," and you won't be able to type in them. 

By using Adobe tools to fill the form or by placing fields within Docusign, you ensure that the information is captured correctly for electronic signature.
