I think I figured it out but it seems buried.  1. Go into edit mode as you show above 2. On the right click "All Pages"3. Click on "..." beside the interface name4. Click on "Rename"   

If I do that and go into "edit" mode I still do not have the gear or ability to change the interface name.  Am I missing something?

I am having the same issues.  There is no gear button at the top.
