Creating Clamped Connections with gaskets in solidworks routing

Hello All--

I am trying to create a connection with two ferrules and a gasket between them. We use a sanitary clamp to secure the tubing. I can insert one ferrule and a gasket, but I am having trouble with inserting the second ferrule.  When the second ferrule is inserted, It snaps incorrectly.  Does anyone have some suggestions?  I am using Solidworks 2012 sp 2.0. 

Thanks.
