The Date range field within the content type settings for Date Popup Authored is displayed incorrectly due to a regression introduced in #925350: Vertical tabs broken. An issue with Drupal core has been opened to get this problem solved: #970426: Regression: Vertical Tabs styling on input elements overrides specifically set FAPI keys

This has been held up in the core issue queue for quite a while. It doesn't appear to be a problem using the default environment (i.e. Seven as the administration theme), so I'm marking this as won't fix. If a theme wants to handle fields in vertical tabs, it needs to override misc/vertical-tabs.css.
