What happened?

Custom radio button values do not appear in the variant list or dynamic variant titles.

Steps to reproduce

1. Create a field to be added to a product’s variants (call it 'myField'), set the field type to radio.
2. Add an option with the label 'One' and the value '1'.
3. Enable 'Allow custom options'
4. Create a new product type (call it 'myProductType')
5. Under settings for myProductType set the variant title to be '{product.title} - {myField}'
6. Add myField to myProductType’s Variant Fields tab
7. Create a new product using myProductType (call it 'myProduct')
8. Create a variant of myProduct selecting 'One' as a the value of myField.
9. Create a second variant of myProduct creating a custom value of 'Two' for myField (Note: there’s no way to set the value, only the label can be set)
10. Order the variants as a list, use the View dropdown to show myField
11. The first variant will have a title of "myProduct - 1" and the myField value of "One" (this is as expected)
12. The second variant will have a title of "myProduct - Two" and the myField value will be blank.

Expected behavior

Custom radio options should behave identically to pre-defined radio options.

Actual behavior

Dynamic variant titles use the label, not the value of a custom radio (unlike pre-defined radios) and neither custom radio labels nor values appear in the variant list.
