Karma Run Complete, Exiting multiple times

My Karma tests are running with locally and with SauceLabs successfully, but they run three times. You can see some of the same messages when I run with debug mode. Any ideas on this?

My set up:

• Angular (2.0.0-beta.7 + necessary includes)
• Karma (0.13.21)
• Jasmine (2.4.1)
• Karma Jasmine (0.3.7)
• SauceLabs Connect (4.3.13 linux)
• Karma Sauce Launcher (0.3.0)

Also breaks without SauceLabs, when ran locally

karma.conf.js:

module.exports = function (config) {
    var launchers = {
