Lease expiration not being enforced?

[PcGuy]

Six days ago I had an iMac attached to a wired connection for 2 days. It has since been removed. Last night I logged into my Asus AC-86U w 386_2_6 firmware and noticed that an Apple Device was connected to a wired connection here with an Automatic IP. Since I only have 3 Apple devices all of which use wifi I know it was not my devices. I had to reboot the router to get the device from showing up in the client list. My question is should this device lease not have expired since the lease time is set to the default 86400?

The Client List (network map) is not necessarily the same as DHCP Lease status. Client List can get stuck/stale. Check the System Log / DHCP leases tab to see if the lease is still present.
