Revit Rebar Schedule Total Mass Problem

[f.kirmizidag]

Dear all,

I created a schedule for rebars. But if i set Calculate Total, Mass parameter (Masse) gets higher than actually is. It is multiplied by random parameters which i cannot obtain what it is. I couldn't figure it out. I get wrong total mass eventually. I'd be appreciated if someone help me.

Under sorting and grouping ... Check the itemize every instance check box 

When it is unchecked and you calculat totals => u get the total per type
