Default category radio button auto set

When selecting multiple categories, none of the radio buttons becomes active unless the user selects one. Submission is allowed and looking at it after submitted, it still doesn’t show any as being selected as default.

Maybe this isn’t a huge issue, maybe one is actually the default in the system even though the interface doesn’t register that. Not sure what the differences are in general operation, but if a listing expires and is downgraded to a package that only allows one category, I’d assume this is where the default category would come into effect.

It would be nice to have the “first selected” category automatically be the default, allowing the user to change that if desired.
