Keep getting followed but they don't show up in the 'followers' count

I keep getting followed and while im streaming it shows up in my activity feed and then in my channel analytics however on my channel page and in acheivements it says i only have 21 followers when 61 people have followed in the last 30 days

Someone Help

That would suggest the people in question unfollowed after following.

Or were part of a group of followbots that have been removed from Twitch.
