Why soft buttons/keys on my Honor 6 are aligned to one side of the screen?

[AC Question]

Hi.. from past couple of days I am experiencing some unusual (!) thing with my Honor 6 phone. The soft buttons/keys (return, home & task) are aligned to one side of the screen and I am facing little inconvenience in dealing with this.

I have not made any changes in the settings of the phone. Please help!

Had the same issue until noticed that "One-hand UI" is turned on.
