Hi egarro,
Unfortunately we can't update the switch because it is used in a critical production system. I had a look through the Juniper PR database in case what I'm seeing is a bug but didn't find anything relevant.
I've included a sample of output from show interfaces extensive below - CoS has been configured on xe-0/0/0 but not on xe-0/0/30:

It's interesting to see that the 'CoS information' portion of the output is there in xe-0/0/30 but not in xe-0/0/0 - perhaps this is due to the custom traffic control profile and scheduler that I've configured?
