A question about Translight

I am trying to use Translight to simulate 2D metallic PC. The predifined system 'Sigalas's metallic system, 2D' can get the good result.
But after I defined my own system based on Sigalas's system, the result seems always the response of the dielectric materials whether or not I checked the 'metal' option. I only changed the control.dat file a little bit and using the cell1 to cell6 in the template folder which generated from the 'Sigalas's system' in the software. Is there any trick to use 'metal' option?
By the way, I can get the same result by changing predefined system to template system if I use the other dielectric system.

Thank you ahead.
