Address Custom Data as Autocomplete-Select doesn't work in Contact's Form

When create a custom field for Contact's Address as an Autocomplete-select, the field in the Create New Individual form doesn't have the autocomplete behaviour. Actually a flat textbox is displayed (without the lens icon in the right side) and no options list is shown when you type in.

The same field in the Advanced search is displayed correctly.
