LuCI displays an incorrect hostname hint

Hi, I have a problem, OpenWRT displays wrong hostname in "Active DHCPv6 Leases"
section for one of my devices.

In the table, host is labeled as todoistFrame (ulnMonitor.lan) when I would expect it to be labeled as todoistFrame (todoistFrame.lan). All devices are labeled correctly in "Active DHC Leases" section. Both devices have static leases set as follows:

config host
        option name 'todoistFrame'
        option mac 'B8:27:EB:30:38:32'
        option ip '192.168.1.64'
        option duid '00010001298602100013ef400927'

config host
        option name 'ulnMonitor'
        option mac '00:13:EF:40:09:27'
        option ip '192.168.1.48'
        option duid '000100012d014e4b0013ef400927'

The only clue I have is the fragment below from running command ubus call luci-rpc getHostHints, where ulnMonitor is associate with its own address (fd37:7772:7f70::48) and the address of todoistFrame (fd37:7772:7f70::64).

"00:13:EF:40:09:27": {
                "ipaddrs": [
                        "192.168.1.48"
                ],
                "ip6addrs": [
                        "fd37:7772:7f70::48",
                        "fd37:7772:7f70::64",
                        "fe80::ba14:c39b:b348:f7e4"
                ],
                "name": "ulnMonitor.lan"
        },

Is there any way to fix this?

Honestly, I'm surprised static devices are showing up at all as a lease.

I've never seen that.

I do not use IPV6 (I have but I disabled it) and when I set my pi-hole as a static address on both 4 and 6 LuCI did not show it in the Status/Overview page.

Now: the reason I ditched IPV6 is because I sucked at it. So I may have had a bad config and yours is right.
