Why doesn't Sluggable work from within a package?

Question

Laravel

I have a Category model and it uses
use Cviebrock\EloquentSluggable\Sluggable;

<?php
 
namespace App\Models;
 
use Illuminate\Database\Eloquent\Model;
use Spatie\Translatable\HasTranslations;
use Cviebrock\EloquentSluggable\Sluggable;
use Kalnoy\Nestedset\NodeTrait;
 
class Category extends Model
{
    use HasTranslations;
    use NodeTrait, Sluggable {
        Sluggable::replicate as replicateSluggable;
        NodeTrait::replicate insteadof Sluggable;
    }
 
    public $translatable = ['name'];
    protected $table = 'categories';
    protected $fillable = ['name', 'slug', 'parent_id', 'owner'];
 
    public function sluggable()
    {
        return [
            'slug' => [
                'source' => 'name'
            ]
        ];
    }
}

I decided to put it in a package and pull it out of the package to create categories, but the sluggable does not work in the normal way, what could be the reason?
I'm attaching screenshots from tinker where I'm trying to create a category from under different spaces:
App/Models/Category works out sluggable with a bang.

StarterKit\Core\Models\Category also the same model only in the package does not want to throw sluggable.

[Vanga-mode-on] Because you didn't register the model observer.
