Document editing from Sharepoint with World template

Hey!

I expreienced the following problem after i upgraded to 2016 ProPlus Office 64bit the workstations. 
When i would like to open a document from a Sharepoint based site from the Document tab to edit with it's template in World, i realized that in World there are unfillable fileds and it says Not available at the moment. I can add only Hungarian screenshots from the error if you need them in English notify me please.

 

The only field i can fill is the Subject but in the other fields i can't even click in. 

When we used 2013 Office pack, there was no problem about this, also i have already tried to install AccessDatabaseEngine and Runtime to solve the problem with no success thats why i am trying to find an answer in the official forums.

 

Thanks for you help!
