Cannot see branch (and other) test coverages

I'm trying to view various test coverage statistics e.g. Branch coverage but can only see a statistics column in my 'Show Coverage Data' panel with 'Line' and 'File' coverage.

I have turned on ''Branch coverage' in Build, Execution, Deployment > Coverage > Python Coverage > 'Branch coverage' and ran my configuration 'with coverage' but it makes no difference to what I see.

Is there something I'm missing here?
