Subscription date got it wrong?

It's been 24 hours since I emailed billing@nextdns.io

While waiting for their reply, have any of you ever encountered this issue? And why does my subscription resume its date right where I left off? I canceled those subscriptions back then, and I only paid for one month. After a couple of months, various DNS providers that I tested... I decided NextDNS was the best for me, so I chose to pay for one year. But as you can see in the picture, it resumes where I left off. I will update if there's any reply from NextDNS.
