Need Help Please:Size/Gauge doens't display on BOM

Hello

I have a problem with the Route property in Solidworks electrical 3D, the  Size/Gauge doesn't display on BOM when I prepare the route for a flattened drawing (Flatten Route).

1-I make a simple scheme in Solidworks electrical 2D [figure 1].

2-And I pass to mode 3D [Figure 2].

3-Then I displayed the scheme in Flatten route with circuit summary BOM [Figure 3].

4-You Can remarque that size/gauge column does not display any value and doesn't match the table in solidworks 2 D [Figure 4 and 5].

5-And when I try to edit route and click on Electric attributes, the properties don't display any size/gauge value [Figure 6].

Can anyone explain to me what's wrong?

I will be grateful if you could help me friends.

Thanks
