Either your decal is missing on both sides of the mower, or you should read the instruction manual and it would have told you where to look for height of cut.
Here are the pictures I have to show you what I have. One is of the owners manual page, one is of the indicator I think you are describing, which is on the Hydrocut, not the DD series, and the other is of my actual mower.
