[HLSL] Problems with 2MGFX

Hi I’m using MonoGame_Develop_Win_3.3.0.1963 and I’ve been playing around with shaders trying to get the hang of HLSL and I’ve noticed whenever passes contain anything related to Stencil or ScissorTestEnable it causes 2MGFX to error with the message “Unexpected token ‘S’ found. Expected CloseBracket”

for example

technique Clear
    pass Alpha
        //StencilEnable = False;
        AlphaBlendEnable = False;
        CullMode = CCW;
        ColorWriteEnable = Alpha;

        VertexShader = compile vs_4_0_level_9_1 VS_ScreenCopy();
        PixelShader = compile ps_4_0_level_9_1 PS_ClearTarget();

compiles fine but if I uncomment StencilEnable I get the error on compile.
