Fix 36Hour.#.ChancePrecipitation alignment

ATM there are 3 label 36Hour.#.ChancePrecipitation where # is 1, 2 or 3, and this is shown in middle of screen with <right>590</right>

idk what correct alignment is supposed to be but <right>90</right> seems to be more or less correct.

It worked when it was 						<posx>590</posx> but now id doesnt and I though Ide have a stab at fixing it.

See screenshot of bug.
