Monobook styling is done on Monobook.css. If I remember correctly, wikis created in or before 2009(?) need to put in various extra styling that the Oasis skin generates on the Monobook.css page. Had to do that on the KFP wiki since it was made in 2008 - have a look. Should still work on the default Oasis skin, though - that's what I tested. Strange that it's not showing up for you.

And by the third skin, do you mean the mobile one? Not sure there's any way to change styles on mobile. Looks like in the URL it says it uses the "Mercury" skin, but there's no such page as Mercury.css. Wouldn't surprise me if Wikia designed it like that.
