Grump not fixing my issues

[GeoffreyOlivier]

Hello, I launch this command :
php vendor/bin/grumphp run
After I have all errors, for exemple :

`FILE: ...-content\plugins\sync-woocommerce\src\Plugin_Factory.php

FOUND 6 ERRORS AND 1 WARNING AFFECTING 6 LINES

1 | ERROR | [x] Header blocks must be separated by a single blank
| | line

| | format

PHPCBF CAN FIX THE 5 MARKED SNIFF VIOLATIONS AUTOMATICALLY
`

And I have this question on the end :
I can fix some stuff automatically, do you want me to? (yes/no) [no]:
When I write yes nothing is fixed.

How can I fix automatically?
Thanks
