Why does this forum's Invisible mode not make you Invisible?

[Core]

General Settings: User>Login & Privacy
Invisible Mode: Invisible Mode on
Invisible mode allows you to browse the forums without appearing in the 'Currently Active Users' lists.

BUT, if I check this list I see myself...wth? Are there any admins fixing any of these borked things?

[NoIDs]

You will see "yourself*" in the list, but others will not - so not "borked", lol. I do not think the admins fix code, i think they wait for vBulletin to fix the bugs.
