Expiry date wrong on Gift Card plugin

Hi, on the GIFT4U – Gift Cards All in One for Woo plugin how does the date picker work? Does it actually send the gift card or voucher on the said date?

If so, how would I know what time it was sent?

Another issue, I have is I set the expiriy date as 732 days because I want it to expire after 2 years. The problem is the expiry date is reflecting as same day of purchase which is not ideal.

How do I set the expiry date to automatically show as 2 years in the pdf after they purchase the voucher.
