[Sentry.io] - Keep getting reports for deleted project/account

Hi, recently I started using sentry.io and I really like it! While setting up, I probably have done something wrong though. I have recreated a project and removed the old one. But I keep getting weekly reports for both projects. In my account however, I only have 1 organization and 1 project. Is there anything I can do about this? Thank you so much for your help!
