So using the following options in list with type radio is causing issue when you select 'No'
[{ label: 'Yes', value: true }, { label: 'No', value: false }]
On selecting 'Yes' its setting model value correctly which is true but if select no then its setting model value to then entire choice object which is {label: 'No', value: false} which seems very odd as I was looking at the component source code couldn't pin point the issue
