Saved credit card expire date displaying incorrectly

I just updated to 1.3.0 and enabled the tokenization option (thank you so much for including this!). I processed an order and selected the checkbox to save the credit card information. Without logging out, I added another item to my cart and proceeded to checkout. The option to use my saved credit card is there, but the expires date (i.e. Visa ending in 1234 (expires 01/20)) is different than what my actual card expiration date is. Both the month and year are different. Even with the incorrect expiration date showing, it allowed me to process the order, so the tokenization process works, but I don’t want my customers to be confused by seeing an incorrect expiration date shown. Is this a known bug, or does this date represent something else?

Thanks
