A family of Microsoft word processing software products for creating web, email, and print documents.
I'm not sure if it will help anyone else but I figured out how my system was doing this. I changed True to false below.
Set wddoc = wdapp.Documents.Open(FileName:="c:\templates\contracts\Agreement.docx", ReadOnly:=False)
My process has been this was for 10+ years with no issue populating the bookmarks. I'm guessing it is a security update that changed how it processes.
Like I said probably just my condition but wanted to put it out there.
