Don' know but I cannot make the change directly on GitHub (a bit lazy right now to pull the branch). But here is the code you must replace:

```php
// We check if the route name contains a "/", which indicate that we have a child part
$parts          = explode('/', $options['name'], 2);
$childName = isset($parts[1]) ? $parts[1] : null;
$name         = $parts[0];
```
