-_Tube option localization

I’m trying to run -_Tube from a C++ plug-in. I noticed an new option appeared in Rhino 5 : _BothSides. And I don’t manage to unset this option.

What I’ve tried is something like this:
-_Tube _DirectionConstraint=_None 0,0,0 _Diameter 50 _Diameter 100 _BothSides=_No 200,200,0.

It works in English but not in my local language (for instance, in French).

P.S. : Manually set the option to _BothSides=_Yes before trying this.

Yep, looks like a bug to me…

Got it, thanks.

It seems to be solved.
