No ID in DHCP table

I am using an hAP ac2 as an extender from a wAPac LTE.
They connect over the 5Ghz WiFi.
When I check the DHCP table in the DHCP server in the wAP I can see the hAP’s IP and mac but not the ID.
If I shift to another hAP it shows the ID
Both hAP’s have the same configuration and ROS version (6.47.6) The wAP has OS version 6.46.3
Anyone have any ideas?
