Hibernate apps but they wake back up... Facebook for one topic

If I hibernate an app like Facebook, its hibernated.. why does it wake back up? how can it wake back up if I dont open it or call it or do anything to share to it etc...Makes no sense.

I am rooted with greenify installed, I hibernate Facebook. Facebook is set to no chat, no notifications, nothing.. it has everything you can disable disabled... yet time after time again of hibernating it, I wake my screen up and do a manual manual hibernation OR i open greenify and Facebook is right there under Apps that will be hibernated soon. i can see the message tha says "Facebook was hibernated when i do a manual hibernation but it always seems to come back on its own.
