Выпуск JComboBox

У меня есть задание в классе CS12, который создает программу, в которой можно объединить JRadioButon/JCheckBox/JComboBox вместе.

На данный момент я очень смущен JComboBox, я не понимаю, что именно мне не хватает в части ActionListener.

Сначала я не могу выбрать какой-либо вариант из третьего столбца (Цвет и интерьер), он просто не отображается на ярлыке, созданном в том же столбце.

Во-вторых, я не вижу значений JCheckBoxes созданных во втором столбце, прежде чем я выбрал провинцию из четвертого столбца.

Будем принимать любые советы, спасибо. // простите за мой английский, я не носитель языка.
