The drop-down menu options are preloaded with a set of standard values, but can be customized by you. Whether it's an option that's not there, or something you want to remove, it can all be easily managed under the drop-down menu option in the admin section.
Click edit for any one of these drop down menu fields, and you'll be presented with a list of the existing values.
You can edit, delete, or merge the option.
