Answer 1

You are missing list-group first ul element. This is reason all column width are not same width.

Event if you use same class for width as it in percentage so it will change its outer space according inner element how its occupied using padding or width or height css style. if it was fixed width its not impacted whether inside element how its occupied.

Answer 2

Nothing else, You are just forget to give list-group class to first ul.
