Don't worry! This is just a reservation made to verify that the card you added is valid and will be automatically retracted once the card is verified.
When connecting a card as a payment method to your Subscription this card will be verified and if valid stored with your subscription. If the card is not valid you will not be able to add this to your subscription. Our Payment service system verifies cards by running a $0 or $1 transaction and then automatically voids it. This is the reason you might see this as a planned transaction on your credit card statement.
