Revit 2010 - Conceptual Mass turns Transparent Purple

All,

I am just getting into th eConceptuial mass in 2010 (I will be upgradign to 2011 shortly but that is not at issue right now).. My main issue is that if I create a new Conceptual Mass family is is opaque grey. If I place this family it is opaque grey. If I then edit that family (select it and say 'Edit Family')...the first edit to the mass (whether shifting a point, a face, an edge...anythign really) the mass goes transparent purple and I cannot get it back to the previous 'look'. Of course I can change the material of the mass but that is not at issue.

I wan tto know why it does htis and if this action a setting or something?

Thanks,
Drew

Thanks any way,
Drew
