    Untick static, or lightmap using the drop down arrow.

    There are several options, depending on what you want to achieve:
    If the object should contribute to the lightmap but not be lightmapped itself: Lighting window -> Object tab -> set Scale In Lightmap to 0.

    Assign a Lightmap Parameters to the object and check Is Transparent. This makes the object appear transparent during Global Illumination lighting calculations.
    Backfaces are not contributing to and light travels through the surface. This is useful for emissive invisible surfaces.
