How 'bout some grey cubes?

Those grey cubes aren't supposed to be there. If you go onto your gamecube console, play Mario sunshine. Play the shine called "Secret of the dirty lake" Once you get to where you re supposed to go you will see the blue and red platforms without the grey cubes. But if you go to the same level on dolphin, the cubes are there. Running build 3.5-1085. Why are the cubes there, and can they be fixed? They are also there on the edges of the cube that you use to get up to that part. Its not a big deal. But if this was corrected, it may correct more issues in the game and in other games
