Why are '>>>>>' symbols appearing on my view even after deleting vendor and cache in a knp paginator setup?

Question

Do you understand why I have these '>>>>>' displayed on my view? It doesn't correspond to anything, I can't find the problem with knp paginator. I already deleted the vendor, the cache. The '>>>' are adjusted according to the pagination parameters. ('page', 1), 10

Thanks for your help :)

knp paginator

 #[Route('/admin/annonce', name: 'admin_ads_index', methods: ['GET'])]
    public function index(
        AdsRepository $repository,
        PaginatorInterface $paginator,
        Request $request
    ): Response {
        $ads = $paginator->paginate(
            $repository->findAll(),
            $request->query->getInt('page', 1),
            10
        );
        return $this->render('admin/ads/index.html.twig', [
            'ads' => $ads,
        ]);
    }
