Problem with Workflows Sharepoint 2016 -office 2016

Hi

I have installed a Standalone SharePoint server version 2016. I have configure workflows. But I  have a problem with work flows in office 2016.

 I upload a document that requires 2 digital signatures  and I start the workflow from SharePoint. Then, if I double click this document from SharePoint and it opens from Microsoft Office version 2010 or 2013  it shows a message “This document requires your signature”. If I click  there a pop up widows is appeared containing the key Sign. If I press Sign another pop up window is appeared and asks to digitally sign this document. This second window doesn’t appear on Office 2016. So workflow goes without digital signature.

What can I do?

Thanks in advance
