Document Information Panel - Field - "Currently Unavailable" in Office 365 and Office 2016

One of our clients use Word, Excel templates which has Document Information Panel and few tags and properties.

There is a property called "Author", this property is unavailable to users when they create new documents using Office 365 or Office 2016. Its says - currently unavailable

However if they create the new documents using Office 2010, the property works fine.

Any inputs of this issue please? I recreated the templates assuming it as SharePoint issue, but looks like it is more of local office client issue.

Thanks,

Manoj
