A pretty cool addition, but one with some issues.

From /admin/store/settings/checkout/edit/panes under Customer Information settings, I check Allow anonymous customers to specify a new user acount name and Allow anonymous customers to specify a new user acount password. (BTW account spelled wrong in both lines). Actually, it does not matter whether I check these or not, the option still shows up.

The main problem is that when an anonymous user signs up and specifies an account and password, but uc_roles ignores both. It sets the user name to the user email (very ugly) and sets the password to a Drupal default. Any recommendations for either how to fix this, or for how to hide this option from the users? Any help would be appreciated.
