Issue checking in sheet metal files

I'm not sure if I'm the first to notice this, but when you check in a sheet metal part that has a material assigned to it, there is a greyed out "Cut-List-Item1" underneath the part file.  Oddly enough, when you first make a sheet metal part and try to check it in, there's no problems - it only happens when you assign the material property.

Has this been reported?
