Django-autocomplete-light - "No results found" in browser on startup - after doing one search in admin - results are found in browser again

Question

I have a peculiar problem with Django-autocomplete-light. When I go to my browser and try searching for something I get "no results found" - but when I go to the admin panel and add a model, the results pop up as they should. When I have done this one time, I can go back to the browser and then the results show up as they should. I'm suspecting some caching issue, but not sure how to debug this. Maybe someone can take a look if there is something wrong with my set-up.

models.py

class DogBreeds(models.Model):
    name = models.CharField(max_length=150)

    def __str__(self):
        return self.name


class Advertisement(SoftDeleteModel, TimeStampedModel):
    breed = models.ForeignKey(DogBreeds, on_delete=models.CASCADE, null=True, verbose_name='Hundras')
    

views.py

class BreedAutocomplete(autocomplete.Select2QuerySetView):

    def get_queryset(self):

        if not self.request.user.is_authenticated:
            return DogBreeds.objects.none()

        qs = DogBreeds.objects.all()

        if self.q:
            qs = qs.filter(name__icontains=self.q)

        return qs

Form template

Admin.py

class AdvertisementAdmin(admin.ModelAdmin):
    form = NewAdTakeMyDogForm
    readonly_fields = ('id',)

admin.site.register(Advertisement, AdvertisementAdmin)

The issue was resolved by removing the following lines, as per the recommendation by the good Iain Shelvington!

if not self.request.user.is_authenticated: return DogBreeds.objects.none()
