Unable to add cut list properties with sheet metal flat-pattern in drawing.

Sometime, I would like to add cut list properties with sheet metal part's flat pattern which shows a lot of things like sheet thickness, blank size etc. 

But in some cases, I am unable to add these cut list properties. Why, I can't add this, I don't know. I anybody have any past experience to deal with problem like this, please share your solution with me. 

Thanks in advance.
