Converting comparison .doc to PDF, inconsistent markup on different clients

We use both your document compare and PDF conversion functionality in our product. Recently we’ve observed that in certain situations, a compare document that is then converted to PDF can result in a different output on different PCs. I’ve attached a couple of .docs and .pdfs as an example. In this case, the compare markup formatting is different, but in some cases it is completely absent from the converted PDF.

Do you have any idea what might be causing this? The two PCs have identical installs of our product, and both have Word 2016 through Office 365.
