Dynamic QR code contact not updating with new info

I previously scanned a dynamic QR code contact info and saved it to my contacts. When I saw the person again, their info changed but the code remained the same. I scanned it to update their info in my phone. The contact info updated on the webpage that launched. However, when I click "save to my phone" it pulls up the OLD contact card, not the new one. Why isn't it accepting the new info?
