Missing

Hello, I'm trying to monitor a network with xerox printers, I've installed docker and observium, I can add printers and other devices normally. But when I'm trying to get inc levels of Xerox printers it doesn't seem to work, I saw in the container files that the Xerox MIB is there but on the UI of observium in the list of all the MIBs it doesn't appear like a lot of other MIBs. (I'm running observium on a mac but I don't think it makes a difference anywhere ?)
