Got rejected or it might be a mistake?

I had my amazon SDE-1 loop finished yesterday, and today just an hour ago, I got an email saying that I was not able to clear my software developer interview, but the job ID was different than the one that I applied for and when i checked in my applications page, I found out that my application is still active. What should I do? Am I rejected or is this a mistake Anyone had the same issue earlier. Since i got this email, felt like all my hardwork was in vein. :\ (I’m located in canada)
