In [Multiple Locale Mode](https://faker.readthedocs.io/en/stable/fakerclass.html#multiple-locale-mode) session
```
from collections import OrderedDict
from faker import Faker

locale_list = ['en-US', 'ja-JP', 'en_US']
fake1 = Faker(locale_list)

# Will return ['en_US', 'ja_JP']
fake1.locales

### Should be changed to

```

fake1 = Faker(locale_list)

# Will return ['en_US', 'ja_JP']

# Will return ['en_US', 'ja_JP']
