Conditional groups not working

The conditional groups do not work properly on the frontend. The conditional setup only works once after page load. After that, nothing happens when switching between checkboxes/radio buttons. The conditional group appears only when clicking in another form field.

It is also no longer possible to switch between hide/show options in the backend. It is only possible to show a group if something happens.
