Not all Hostnames and IPs showing, only MAC address

2I have just installed UDT and can only see some IP Addresses and hostnames.  I can only see the IP addresses and hostnames on one vlan.  What do I need to do to get the IP addresses and hostnames to show up for devices on all the different vlans?  I am running UDT 2.0.0.  Yes I know that version is old, but our maintenance expired.
