Unable to see full options (e.g. Actions, Files & Extras)

I have two linux machines (with Ubuntu 16.04 LTS). Both machines run TeamViewer 13. I am remotely accessing machine2 from machine1. Ideally, I should be able to see a full set of options, for example the options in this image

But all I see is some small set of option as shown in the image below (actual image from my machine1 which remotely accesses machine2).

I have used TeamViewer for 6 months earlier with two different machine - windows and ubuntu as far as I remember I used to see full set of option in ubuntu while accessing windows machine.

Can anyone help me bring these full set of option back again?
