First person character controller issue.

Hello,
Firstly, I am a massive newby. I have enrolled in a college course in order to educate myself further (which starts next week). How ever I have been playing with unity by myself for a while now and have successfully built a small island to explore. How ever, when I attempt to navigate the island my character constantly moves to the left. I can change direction as per normal, but if I release any other directional keys it reverts back to its side stepping base.

This is probably a really easy fix, but I have no idea where to even start. I am just using the basic first person controller that is shipped with unity 5.

I found the issue for anyone else who encounters this. I have an Xbox 360 controller and a Joystick plugged in which were interfering. I adjusted the “type” drop down menu in the project settings > input menu to “key or mouse button”. Problem solved.
