jest-cli code coverage only shows zero percent

For some reason, in my new project, my test coverage always shows as 0% even though there are tests and they are clearly running.

Test Suites: 3 failed, 4 passed, 7 total
Tests:       4 failed, 21 passed, 25 total
Snapshots:   0 total
Time:        1.849s, estimated 2s
Ran all test suites.

Is there something wrong with my configuration? My test files are in __tests__ and here is the jest configuration in my config file.
