I am sorry to bother with this beginner things but it seems that I have more than one issue to rig properly. Hopefully it's the last time

So basically, I am trying to rig my character for a side walk cycle. Everything is good but then when I try to move the left leg controller, it responds in a very strange way. You can see in the picture how it distorted my leg, and I just moved up the controller in the Y axis. I tried to move the other controller and beside the two hands, shoulder and pelvis behave in the same way

Thanks
