Weird DHCP issue

I plug my computer into 1 port with Vlan 10. Move my computer to a new port with Vlan 20. Both Vlans have different DHCP scopes. Computer keeps preferred IP of the last IP it got previously even though it is on a different vlan. Obviously cannot connect. Re-enabling the NIC or releasing the IP before moving to new Vlan port and then renewing fixes the issue.

What is happening here?
