This is a fairly recent problem.
Iam on Win 10 Home latest version with all updates.
I am on Office 365 (current version).
I use Adobe Reader DC 2018-011-20040
I have a MSWord file with our logo top left and the address showing Top right.
When I convert to PDF the address part disappears.
I have tried
Export to Pdf
Save as Pdf
and Print using Cute PDF Writer.
Same result each time -the address part disappears.
I sent the Word file and the "failed" pdf file to a friend who is on Word 2013 and he advised he had no problem getting the address showing in pdf format.
Any ideas how to overcome this?
