"Others" label (no replies)

Hello,
I recently noticed I miss some data when using the APIs. After short investigation I discovered I get a raw with label "Others" in the end of the API response:
{"label":"Others","nb_uniq_visitors":254,"nb_visits":258,"nb_events":388,"nb_events_with_value":325,"sum_event_value":325,"min_event_value":0,"max_event_value":169,"avg_event_value":1}
Is anyone know what this label means? Is there a chance my missed data goes there?

Thanks
Guy
