Blocked unknown wifi device still transferring data.

I have an unknown wifi device that is downloading data in PB scale even though I blocked it Thursday last week. Is it a visual bug or real? I have already identified every single device in my network. But this one is the only one I am unable to account for.
@terziyski I used the block list feature within the router. Unfortunately I've already tried looking up the Mac address but it resulted in unknown device. Tried multiple sites but no go.
You can monitor/manage your client devices when logged in via a web browser:
Make sure that this device is in the Deny list:
@Nertip It definitely is a firmware bug. I'm using web UI and also seeing this. At first I thought someone got me. Then I realized my WIFI password is a pain to type, and would take more than a thousand years to bruteforce according to Kaspersky's and BitWarden's password checker. So I went back to really pay attention and noticed the mysterious device comes up every time the router got a hold of a WAN connection. The uptime is about 1 second away after WAN is 'UP'.
Mine shows as connected to 5G band. Blocking this device or not doesn't affect the internet usage at all. If you keep it blocked, it won't show in the web UI clients list, but would come back after the router is rebooted.
