Customizr template control panel issue

The Customizr template control panel, the one that appears on the left, and you check boxes etc to make adjustments to theme. The panel loads but I cannot see the check boxes or all options. It is like the control panel is too large for the space and cut off but there is no way to scroll it to left so I can see the check boxes on right side of the panel.

Hope that makes sense.

Thanks for any assistance,

Paul
