Filter Content By Language when Using the Search API Algolia module in Drupal 8.x

I am trying to configure Algolia on a client website (Drupal 8.x) using the Search API Algolia module [Search API Algolia | Drupal.org]. I am able to index the site content and the records in the Algolia UI show a search_api_language attribute, however, when I attempt to filter by language within Views (eg. [Index Site search index: Item language (= Spanish)]) the content is not filtered. I have added this attribute as a searchable attribute under the index configuration in Algolia. Any advice would be much appreciated. Thanks.
