Missing "New Group" and "New Page" buttons

I don't have a "New Group" button or "New Page" button (there is however a "New Event" button).

Here's a screen capture to illustrate: https://promethean.tinytake.com/sf/MjkyMTQ4N184NzY3Mjg0

Here it is on your Demo: https://promethean.tinytake.com/sf/MjkyMTQ5Ml84NzY3Mjg5

Please advise how I activate these 2 buttons. Thanks
