sensu-mail alert

The occurrences parameter on the check does not work as it should..I'm getting spammed with emails because the default occurrences is 1. Even if i change it to 20 i still get an email for every critical occurrence. I checked sense-client and server logs but nothing which would tell me the reason why this is happening.
