Drop down button in Mobility

Hello All,

I have introduced a new module PM in mobility. 

The issue is with the back button which is visible instead of dropdown option with all the other out of box options available.

The back button is am not able to remove it and introduce the drop down option. Once i am inside the PM module the back button does not work and I am not able to go back to Home page.

Please can somebody help me with the issue.

Thanks,
