URGENT: People without a payment in stripe are showing Active membership

I am pretty sure this occurred after I switched from Stripe single payment to Stripe subscription for my main membership.

I am seeing a LOT of people with Active memberships but without a payment associated to them.

Need to know what is going on ASAP, I am manually deactivating them right now, but I may have lost the opportunity to close 50-100 potential customers because of this.
