You seem to be confusing Overseas Territories with Crown Dependencies.
The Crown Dependencies are not part of the United Kingdom but are internally self-governing dependencies of the Crown. The Crown Dependencies are the Isle of Man, the Bailiwick of Jersey and the Bailiwick of Guernsey.
The Overseas Territories are: Anguilla, British Antarctic Territory, Bermuda, British Indian Ocean Territory, British Virgin Islands, Cayman Islands, Falkland Islands, Gibraltar, Montserrat, St Helena and Dependencies (Ascension Island and Tristan da Cunha), Turk and Caicos Islands, Pitcairn Island, South Georgia and South Sandwich Islands, Sovereign Base Areas on Cyprus.
