I had a situation in which I needed to activate some rotational degrees of freedom on the independent side of am RBE3 due to geometry (linear set of points). I noticed in the model sometime later that those same rotational degrees of freedom were activated in a different RBE3 in the model. I did some testing, and if I go Edit->Element and select any RBE3 in the model, change a DoF setting and then do Edit->Element on a different RBE3 in the model it will show that same edited set of DoFs. What gives? There isn't some limitation I'm unaware of in Nastran that requires all RBEs of a type to have the same DoFs is there?
