Draftsight 2018 issue when copying geometry

Hallo, I have an issue using DS2018 Professional 2.1 - When I copy (but also using mirror) a geometry, the copied element loose the color.

I think this happen because the color property of the geometry is set on "by layer". I tried to set the flag of the copy command "copy on active layer" to "off" but the problem still persists.

Does anyone have the same issue?

Thanks
