I think the underscore handle in β_@orangepill.devβ is currently being treated as a @name of the NIP05 identifier by clients. I mean you could have a username as @bobross in your profile and a NIP identifier as _@orangepill.dev but that β_β is treated as a NIP05 name in the Nostr.json file.
So I added that to my Nostr.json and created a new pubkey/user to test. See this user:

I added β_β: βhexpubkeyβ
