Headings in Word become images when exported to PDF
I have a document that uses multi-level numbering (1., 1.1, 1.2,...2.,...) for Heading 1 through Heading 5. A tab separates the autonumber from the heading text. The font is Arial for Heading 1 and Heading 2, Times New Roman for Headings 3, 4, and 5. The document must comply with Section 508 accessibility requirements.
I am using Word 365 in Windows 10 and Acrobat Pro DC.
When I export the document to a PDF file, Heading 1 through Heading 5 are no longer text. Instead, each is a pair of images, one for the number and one for the heading text. And Acrobat produces the accessibility error, "Other elements alternate text."
What can I do to ensure that the text remains as text when exporting to PDF?
