Custom manager is not working

[mirodil1]

I've created new custom model manager, but when getting list of objects last added ones are not included, even if I clear cache after creating also not helped.
managers.py

from parler.managers import TranslatableManager

class PublishedManager(TranslatableManager):
    def get_queryset(self):
        return super().get_queryset().filter(news_status="published", publish__lte=timezone.now())

models.py

from .managers import PublishedManager

class News(TranslatableModel):
    ...
    objects = TranslatableManager()
    published = PublishedManager()

views.py

class NewsViewSet(ListModelMixin, RetrieveModelMixin, GenericViewSet):
    queryset = (
        News.published.prefetch_related(
            "translations"
        )
    )
    serializer_class = NewsSerializer
    def get_queryset(self) -> QuerySet:
        qs = super().get_queryset()
        language_code = get_language()
        return qs.filter(translations__language_code=language_code).order_by("-publish").distinct()
