Insert Object (PDF) - Word Document

Hi All,

I'm using Microsoft Word for Mac v.15.38 in my MacBook Pro (macOS Sierra 10.12.6).

I'm having two issues:

1- When I do Insert-->Object and select "Display as Icon", and select a PDF document from my MAC, instead of seeing the PDF as an icon embedded in the document I see the image of the first page and it does not allow me to open it from the document.

2- If I open a word document that was created by someone else under Windows platform which has a PDF inserted as an object, I cannot open it.

Any ideas how to fix these two issues?

Thanks in advance.
