I think we need to clear up some confusion...
So NSCA is properly forwarding to the other XI server, but what exactly are you trying to show us here? You show a number of services with names which don't make much sense, is the system on the bottom screenshot the original XI server, or the one that is being forwarded to? Looks like the original one. Did you improperly assign a few services to that host on the second server? Were these all added through configured objects 100%, or did you do some sort of configuring on that server?
