Passive aligners vs over correction trays
It certainly sounds like you are talking about overcorrection trays rather than passive aligners. Passive aligners do not do anything while overcorrection trays actually pull your teeth closer together. Good luck
Your Invisalign treatment should close up your gaps in the front with no worries.
Often times, a dentist will make a temporary gap between certain teeth in order to move them closer together later on. This technique usually relieves crowding in other areas of your mouth. I would not worry about your bag saying "passive." It sounds like the bigger issue here is the communication between your dentist and you. If you provide more details, I'm here to answer more of your questions, but your dentist is probably your best first resource.
