editing composite queue selectors in explorer

Editing of a composite queue binding's message selector seems to be broken.  

Changing the selector from one value to another value doesn't produce any errors; however, messages are still routed using the old value.  The only ways I have found to make the change take effect are to save the config and restart the router, or to delete the binding and recreate it with the new selector.

Other changes made from explorer seem to be dynamic ... is this one supposed to be as well?
