Problem trying to Kill ORU Msg’s from Core Inbound Thread?

I’m a newbie to Cloverleaf this year.  We are converting over from another interface engine.  I have built and implemented two new ADT Interfaces on Cloverleaf that are working well but having a few issues.  We have all Cerner Msgs(ADT, Orders etc) coming into one thread.  I have it setup to kill any message that is not an ADT, ie. ORM, RDE, ORU but I’m having a problem with the ORU_R01 messages.  See error below.  For some reason it is not killing the message.  I also added the ZDS Segment in the variant so I’m not sure why it is coming up with that error either.  Any ideas?
