vray material conversion bug?

[conceptdesign]

Hard to explain -
1st image is with 2 sided checked in the standard material before conversion from standard to vraymtl (script)

2nd image is without checking 2 sided in the standard material before the conversion from standard to vraymtl (script)

2 sided only works if you have it checked prior to the converion - it this how it is supposed to be?
Thanks
