Teamcity Notifications being sent for a project that doesn't exist

I have TeamCity Professional 7.1.1 and I have a project set up. At some point my notification subscriptions got messed up and now I am receiving notifications for a project that no longer exists.

For example:
Project 1 build failed (however this project had been deleted, so I don't understand how I am receiving notifications)
Project 2 build failed

Additional note: The build number for Project 1 continues to increment as well.

Ultimately, my question is how can I correct this bad data? I didn't find anything in the notifications documentation at http://confluence.jetbrains.com/display/TCD7/Subscribing+to+Notifications
