Multiple showings of AngularJS Unit Tests in VS2015 Test Explorer with Chutzpah and Jasmin

I wrote some Unit Tests for my AngularJS stuff and use Chutzpah to run the tests in VS. That works like a charm but every test shows up 3 times in VS Test Explorer. Any idea why? My chutzpah.json looks like this:

{
  "References": [
     { "Path": “Path of needed file” },
     { "Path": “Path of needed file” },
     { "Path": “Path of needed file” },
     { "Path": “Path of needed file” }
  ]
}
