Series 1 shows up in hosting stats

What is "Series 1" in Twitch Stats for hosting mean? 

If you have checked your stats on the dashboard for who is hosting your channel, pretty sure you will see something called "Series 1" in the list. Here is a screenshot of today's hosting stats from my channel.

• Series 1: 40

When someone hosts your channel, they will show up on the dashboard in the section right under playing. Series 1 has never been listed there so I started to wonder what can this stat mean that's showing up here?

Oddly enough while checking other stats out, I found a link! Here is a screenshot of the same Video Play's section but with a different filter by which is "Player Type".

• android: 40

Turns out its something related to android and/or mobile users and may have nothing to do with hosting.
