DHCP Option 82 not working


What am I missing to get Option 82 working? On the AP, we have turned on Remote ID Type to “CPE Address”:

I then delete a DHCP reservation in our Mikrotik for a customer, reboot his router (to force a new request) and when I look at the new request, there is no Remote ID:

I feel like I am missing something obvious. We are running Firmware on the AP and on the CPEs.
