DHCP Table Question

DHCP Table showing multiple IP’s to some devices. Some devices show up anywhere from 3 to 20+ times in the DHCP Table on the firewall. Seems to be a new behavior.

The way it shows up is Device1 with IP and mac then the same name Device 1 with a second IP and no mac showing additional times. Only for a few devices. Have had one device take 34 IP’s and others take 3. This fills up the DHCP table quickly and no more leases can be given.
