How to scale a Slider Handle Knob with anchors?

Hey, i can’t figure out how to properly scale a Slider using anchors. When i set anchors for a whole Slider, it rescales and streches almost good, but it’s handle knob streches only in y-axis, so my ball-knob becomes oval-knob while playing… I’ve been trying setting anchors for a handle itself, resizing Handle Slide Area and changing it’s anchors, but nothing worked for me :frowning:
Could anybody help me?
