For my iPhone 6s, I found this:
iOS 14 introduces a new Wi-Fi privacy feature. When an iPhone connects to a Wi-Fi network, it identifies itself with a randomized MAC address. The MAC address randomization behavior only generates a new MAC address once for each WiFi network a device joins.
Also found this:
Disabling MAC Randomization
1. Open the Settings on your iPhone, iPad, or iPod, then tap Wi-Fi or WLAN.
2. Tap the information button next to your network.
3. Turn off Private Address.
4. Re-join the network.
I hope this helps others
Cheers

Did you reset via the pinhole? A software reset won't clear the entries. You need to hold the reset until the LEDs flash, that may be 20-30s.
If you need to identify devices then the only sure way is to power them all off, reset the Hub & then reconnect them one at a time.
Have you ever set static IP addresses on the laptops? Although if you had on Plusnet, their Hubs are just rebadged BT Hubs, so shouldn't be an issue.
Ahha! A secret pinhole. I'll dig out a magnifying glass and look for it.
No, I haven't set static IP's for my laptops. Is that advisable?
Static IP addresses aren't generally needed except maybe when sharing drives across the network. But as I said, the Plusnet setup would have been nigh identical assuming you were using their Hub.
Se how you get on with the full reset & we'll go from there.
