Who runs the website for dmv.ca.gov. They got a bug (I think)

I cannot get through their Vehicle registration form.

I fill out all the forms and at the end click "confirm and submit".It then send me back to the first page with a validation error saying the State "field is required".

I fill it in and go through the forms again, click "confirm and submit" and get the same error.

I've tried Brave and Chrome. I've tried different addresses. I've cleared the cache. I've talked to the reps.

Anyone know how I can file a bug OR know a way around it?
