I’ve had that happen with trying to paint oil-stained (as a finish, not like motor oil or something) wood with interior latex. It really doesn’t like this and will let the oil bleed through, cure improperly, anything but go on and look like fresh paint. My guess is the cigarette tars/oils on the walls did the same thing. I read up on this (was years ago) and I think there’s products designed for this (maybe a oil/latex interface primer of some kind). Or you just clean really hard, or use oil-based paint.
