Disconnect All Channels VI with Virtual MUX

I'm getting error -29038 when I use "niSE Disconnect All.vi" to clear all channels of my MUX Virtual Expansion 128 channel mux with single channel exclusion. Each NI mux card is 64 channels, each card's com0 channel is physically connected together.  When I open a virtual session, close 1 of 128 virtual channel, execute Disconnect All vi, the vi throws -29038 error on the second mux.  (I closed a channel on the first mux but they are Virtual right).

 

Now it makes sense to me if I have channel exclusion on all channels of the virtual mux, at any time there is only 1 channel closed.  This vi should close that channel on either mux since its Virtual mux if I have this correc.
