Tried creating blog in geometrix blog page (Geo Blog). Blog got created successfully. But author name is not getting displayed. 

Author property  under /content/geometrixx/en/blog/2015/05/test-sample  is also empty[img]blog-author.png[/img]

It is working fine in AEM6 but not in CQ5.6.1. Can someone help me on this? Thanks in advance
