>Do you mean that the default styling of using empty & filled circles to display selections is confusing?

Yes. Most of the time, radio buttons are mutually exclusive and you can only choose one. Check boxes on the other hand are, most of the time, cumulative.

i.e: if you want to signify you can select multiple items, you use check boxes. If you want to signify you can select only one item, you use a radio button.

I'm a simple person conditioned by years of this pattern, but I think you'd find the same sentiment if you search for "checkbox vs radio button".
