The router shows 2 MAC addresses for the same wifi NIC

The problem exists with routers WR842ND V 1 and WR1043ND v1
I have a laptop which runs Ubuntu server 22.04.01 and is connected using WiFi to a TP_LINK TL-WR842ND or TL-WR1043ND router.
I have reserved the ip address 192.168.11.206 for the laptop.
Some times the router allocates a dynamic ip address to the laptop but when it does that the MAC address is different than the MAC address of the wifi interface.
I use the ifconfig -a command to get the MAC address of the laptop’s wireless card.
wlp9s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.11.100 netmask 255.255.255.0 broadcast 192.168.11.255

The laptop is named Vertiskos. As you can see in the router has allocated a second dynamic ip address to the laptop.

The ifconfig command shows ip 192.168.11.100 for MAC address 68:5d:43:c9:91:ae but the router listing shows that ip address for MAC D6-6E-0E-C9-91-AE
When I reboot the router the dynamic address initially is not allocated but sometime later the problem reappears.
I have the same problem with another TP-LINK router WL1043ND. I think both routers use the same software. Al least the GUI is the same.
Any suggestions are welcomed.
