DISCONNECT PASSCODE?

hey guys. I have been using zoom like most of you for years! I have always had a waiting room which is fine... but over the past few weeks, suddenly, all my clients via my CRM need a passcode to get in. 

I have gone into my settings and disabled "passcode" but it is still requiring people to come in with a passcode, and no waiting room... despite waiting room being enabled. please help?
