Missing Items in Timeline Setting

For some reason, when I checked the items in Timeline setting in Admin, I don't see some items such as Videos (add item), Photos (add item), Blog (add item), Groups (add item) etc.. please see attached screenshot.  For this reason, my OUTLINE on the front page is not displaying anything. I was wondering if there is a way I can add/update these items in the Timeline setting..

Your assistance is very appreciated.. 

Make sure you added those modules. admin, modules, add & manage
