Router issue 6.18.01 Pro

Router inspector will not go away.  It requires task manager to kill Matlab.  

1. Start a new signal flow.
2. Remove deinterleave and interleave.
3. Add a router to the signal flow.
4. In the args for the router numInPins = 2 and numOutChannel = 2
5. connect signal flow inputs to both router input pins.
6. Propagate changes.
7. Open router inspector and select channels.
8. Run then stop.  Close router inspector. (it should close at this point)
9. Open router inspector.
10. Change router arg numInPins to 3.
11. Now try closing the inspector.  It will not close. When you close the signal flow it does not close. The only way to recover is to kill Matlab and start over.

When you try to exit Matlab you get this error:

Struct contents reference from a non-struct array object.
