Contact 'World Region' Field not functioning properly in Search Builder
'Search' -> 'Search Builder'. Search for 'Contacts' -> 'World Region' -> '='. Upon doing the above, the user is presented with a text box instead of the expected dropdown menu.
If the user proceeds to use the unexpected textbox and manually type in the World Region they are searching for, they get an error of the following kind:
Europe and Central Asia is not of the type Positive
