Commits are not grouped by type

Hello

I'm using the CLI version of standard-version, but I don't understand why the commits are not grouped by type when the changelog is generated.

For example the generated output looks like

### Features

* **auth:** add box id to token summary ([azerty](https://bitbucket.org/xxx))
* **auth:** add token request to a REST service ([azerty](https://bitbucket.org/xxx))

To generate my changelog I just use the basic executable

./node_modules/.bin/standard-version

Maybe I'm doing something wrong?

Thanks for your help.
