Membership: Paypal payment showing as timed subscription when mode set to infinite

I ran a test purchase for one of my Membership subscriptions, which is supposed to be a lifetime subscription because I set the Mode to Infinite. However, when I arrive at Paypal to pay for it, it says "$xx for one day". My period is set for one day, but that shouldn't matter because the mode is infinite right? How can I make it so that the payment has no time length associated to it?
