Backspace over what you typed in and press the drop down. You should then see a list that shows custom locations, containing the ones you previously typed in. At least that is how mine is working. If the field contains something I typed in (and did not select from the list), I do not see the list as an option in the drop down.
But as long as I backspace over the typed entry, I see custom locations and can select something.
