Fix duplicate result in TMDB api calls

[moallemi]

While integrating The Movie Database (TMDB) API into our application, we have encountered a recurring issue where certain items (movies, TV shows, etc.) are being returned as duplicates in the API responses. This redundancy not only affects the efficiency of data processing but also impacts the user experience negatively.

Steps to Reproduce:

Make an API call to TMDB with a specific query (e.g., searching for a movie or TV show).
Observe the returned results.
Notice that some items appear more than once in the results, despite having the same TMDB ID.

Expected Behavior:

Each unique item should only appear once in the API response, ensuring that the data is not only accurate but also optimized for processing.

Actual Behavior:

Duplicate items are appearing in the API response. This is not consistent with every call, but it occurs frequently enough to be a significant issue.
