Why path finding AI is not really avoiding the obstacles?

I have a script were my AI character moves to point a to point b using path finding. Though my AI doesn't really avoid the obstacles. He turns for a little bit when the Path is written but a second later he moves directly to the direction to the target point. Please help?

**NOTE: **The path finding part is in the MoveToSpawnPoint() function (Lines 112-128).
