Entries in group/WL GA without belong to either one

Its not an SGTools protected leaked link, just a regular WL/Group GA.

The only thing that comes to mind is that the entrees left a group and haven't synced with SG. It's cause for a reroll if they're not in the group anymore.

I think I won't reroll, too many aren't from my WL or groups included (plus the fact it's not an awesome game, far from this).
So my giveaway was for my WL, a "bear group" and the group related to the game Besiege. I don't think that's a problem of sync with SG, they are too many. Then I realised that maybe all owners of Besiege could enter, I checked and that's not even that, majority doesn't own the game. I think I'll just stop making giveaways with multiple groups.
Thanks for your answers, sorry for my english, and thanks RCSWE for your time :)

Ok, just got it, here's the answer for those who can be interested.
Made my research aha, and the result is that they don't onw the game. They're just following the game on Steam, and it seems to be enough to enter a giveaway related to a game group.
End of the mystery.
