Did selecting it solve your problem or does it just not work as expected any more?
(If it does no longer work then it might be a good idea to make a bug report about it.)
Side-note: There is no KiCad 5 release (yet). You are using a development build 
I hope you know that this comes with some downsides attached. (Right now the main problems are lacking documentation and not yet stable libraries.) More details see this faq post, mainly section about release candidates/ feature freeze
