How do i get animations to run correctly

Hi i just grasp mecanim(first time with mecanim animations) and go the animations to play correctly in scene for mobile

my problem is my character runs right and left only with Idle being the go between ...when character runs left or right he actually runs LEFT or RIGHT lol meaning theres a curve to it i would like him to run along the x axis or atleast in a straight line to the Left or right

is this an easy fix?

the character was bought off the asset store which im assuming came with default animations thanks in advance guys.
