Hi there. I don't think the field "certification" in the discover route is working. I have some search filters and I get the results as though certification hasn't been selected. Here's my code:

const fetchMovies = async () => {
    const queryParams = {
      api_key: apiKey,
      sort_by: sortBy,
      "vote_average.gte": voteAverageGte,
      "vote_average.lte": voteAverageLte,
      "primary_release_date.gte": convertToYYYYMMDD(primaryReleaseDateGte),
      "primary_release_date.lte": convertToYYYYMMDD(primaryReleaseDateLte),
      with_genres: genreSelections.join(","),
      certification: certificationSelections.join("|"),
      "vote_count.gte": voteCountGte,
      "with_runtime.gte": withRuntimeGte,
      "with_runtime.lte": withRuntimeLte,
      page: pageNumber,
      language: language,
      region: "BR"
    };
    for (const key in queryParams) {
      // Just checking if the dates are valid
      if (key === "primary_release_date.gte" || key === "primary_release_date.lte")
      {
        if (!moment(queryParams[key], 'YYYY-MM-DD').isValid())
        delete queryParams[key];
      }
      else if (queryParams[key] === null || queryParams[key] === "") {
        delete queryParams[key];
      }
    }
    try {
      const response = await axios.get(filteredMovieURL, {
        params: queryParams,
      });
      const data = response.data;
      setMovies((prevMovies) => [...prevMovies, ...data.results]);
    } catch (error) {
      console.error("Erro ao receber os dados:", error);
    }
  };

For instance, when using the URL:

https://api.themoviedb.org/3/discover/movie?api_key=MY_API_KEY&certification=L&page=1&language=pt-BR&region=BR

I get all of the movies as though the certification hasn't been specified. Also, I've noticed none of the 20 array elements has a certification field. Here's a screenshot: Mission Impossible fields
