This looks like you are using a library.
So not sure what the library actually called.
Using the Twitch CLI I can see this is for Apex legends.
twitch api get 'clips?game_id=511224'

I am seeing a mix of languages. Note I didn’t supply a start/end times. Since I don’t know what start/end times you used.
So I would suggest that your time restraints rolled 5 clips from japanese streamers.
