I have created a clean install of ZenCart. I created product options, option values, and then used the Attribute Controller to assign them. I selected one of the options as default in the Attribute Controller. If I set the "Option Type" for the "Option Name" to CHECKBOX it works fine (even checkmarks the default). But if I choose RADIO then it shows as RADIO, but all 3 options are selected (checked). If I change it to DROPDOWN, then it shows RADIO with all 3 options selected.

Changing to TEXT or READ ONLY works fine also.

Why doesn't RADIO or DROPDOWN work correctly, but CHECKMARK works correctly?
