Test data after updating

After installing the latest update, our system (a live production system) is full of test data — test users, we are receiving dozens of emails with subject “_Test Email Alert 1” and body “New comment Submitted created”

Under Communication, there is also something labeled Test Subject and “_Test Communication 1” which I am unable to delete.

Is there a way to completely delete all _Test data?

Under Setup-> Email-> Email Alert, you should see a number of _Test Email Alerts. You can go into each of them and click the “Enabled” button to disable them, then save.

Thanks @Ben_Cornwell_Mott … Got rid of those, but can’t open or modify the _Test item under Communication, any ideas?
