Wow, this is a serious bug. You also can't specify the colors of your conditional formatting. You have to use their 5 presets. I was in the process of switching from Google Docs to Excel but this is a deal breaker. I need specific color-coded cells to do my work. I'll be staying on Google Docs. They let you view all your rules and choose any colors and formatting you want.
