Attached is a part file that I'm having trouble transferring some features into a design library.  I want features from Extrude2 to Extrude5 in the design library, but it seems the presents of Extrude5 is preventing the transfer.  If I rollback to remove Extrude5 it works.

What is it about this feature that is preventing me from adding to the design library?

I'm on SW2009 SP4.0.
