Under ProcessWire 3.0.216 and 3.0.217 DEV with activated Debug-Modue the input field for the option Page Reference -> Label field -> Custom format (multiple fields) is not shown. I think this is related to the current jQuery update, because the input field "Inputfield_labelFieldFormat" below it remains hidden via ".uk-hidden".
