R8000 X6S reservation not given to devices

Last week I replaced my X6S with Nighthawk AX6200 RAX78. The RAX78 didn't work out because the WAN port is defective. I opened a ticket with Netgear Support but the didn't respond to my case so I decided to return the RAX78. Before I swapped out the router with the aging X6S, I restored it to factory default and restored the latest backup. It's still missing some reservations to some devices. BTW, my apple devices are dynamically changing their MAC so I didn't reserved addresses to them. I reserved IP addresses to 10 IP cameras, a NAS, several smart plugs, 4 smarlife wifi bulb sockets, etc. Being able to know the exact IP address of these devices are important to me but some are being missed by the Netgear X6S! So, I'm going to jumpship to a different brand. I have always been a Netgear user but I will try a different brand this time. I have thouroughly researched on TP-Link AX5400 and that seems like a viable candidate that could do what my X6S is serving in my network so I ordered it and it will be arriving tomorrow. The X6S is just too slow for me.
