Line impedance in CST

Hi all,

When I try to check the the line impedance value for waveguide port in cst, from object information of the port, I found the line impedance not mentioned and there are dashed line in the line impedance column. I don't know what's this mean?. I attach the picture for the port information.

Thanks.

you can see line impedance to 2D/3D result

can you upload file?
