How are you testing/verifying the change doesn't get through?  Note that 
if you make the change in the console, the console will not 
automatically refresh.  I would first check the access log on the 
consumer to find the ADD or MOD request, then see if that request made 
it to a master, then see if the master rejected it and why.
