Can't find last 2 Lego harry potter gold bricks! where are they?

Ive been through all the Levels, got all the Crests, students in peril, red bricks,under the Leaky cauldron, Eeylops and characters (but Voldemort) and the gold brick indicator doesn't show anything in the hogwarts rooms. I have 198. I got the Quidditch tent past gold brick, and the one in the clock tower( where you get the Milkman) and the one in the gryffindor bedroom past. even the one in the dragon dungeon. Please help!
