Have a problem with rebars.  The rebar is created by "Wire selection". When looking at "ifc reinforcing base quantities" for this rebar I noticed that Length parameter does not match the real value. Have same problems in all rebars in this layer. 
I am using this parametar value in my "Knowledge report" for summarize the lengths and weight for the rebars. The report will be not correct.

Is there any solution to this problem?
