Possible Bug with the CSS different 'view filters'

When opening CSS file. There is:

a. the checkmark icon: Show only rules that are active for the current element.

b. the eye icon: Show only rules that are visible for the current page view size.

The second option doesnt do anything. It shows the while rules.
On the a. option doesnt show any media queries.
How does this suppose to be work then? Am I missing something?
