Using Acrobat Pro DC to convert a Microsoft Word 2016 document (Mac) to a PDF, most of the document is covered except all the Paragraph Underlines associated with the Heading Style Levels and in Headers and Footers. The style and the look of the document is degraded by the PDF translation process. With a small Word template of this file Acrobat converts correctly. However the file that causes the problems is large 85 MB and is based on the same file template. Any reason for this issue?
