Bitcoin core behind Tor Hidden service problem

Question

Recently I had to reinstall/compile Bitcoin Core in my freshly installed Debian Buster laptop. I followed instructions here for method 2 at the bottom of the site: https://en.bitcoin.it/wiki/Setting_up_a_Tor_hidden_service

But shortly after I started my node, I noticed that the command

bitcoin-cli getnetworkinfo

was reporting 2 onion addresses at the bottom of the returned JSON object, at section localaddresses.

    {
      "address": "rs6srmllckfcveu2.onion",
      "port": 8333,
      "score": 6
    },
    {
      "address": "53hhdjgv4jailcee.onion",
      "port": 8334,
      "score": 4
    }
  ],
  "warnings": ""

These are my settings related to Bitcoin Core and Tor

Bitcoin Core config file

proxy=127.0.0.1:9050
listen=1
bind=127.0.0.1
externalip=53hhdjgv4jailcee.onion
onlynet=onion
port=8334

and in /etc/tor/torrc

HiddenServiceDir /var/lib/tor/bitcoin-service
HiddenServiceVersion 2
HiddenServicePort 8334 127.0.0.1:8333

I also added this to but these lines are for c-lightning node configuration, so I assume they play no role for Bitcoin Core configuration regarding method 2.

SocksPort 9050

CookieAuthentication 1
CookieAuthFileGroupReadable 1
CookieAuthFile /run/tor/control.authcookie

Inside /var/lib/tor/bitcoin-service/hostname I can see only one onion address which is the one in my Bitcoin Core config file.

I already tried to delete my bitcoin onion_private_key file and also deleted my /var/lib/tor/bitcoin-service folder, but still 2 onion addresses are showing up. So, where is it Bitcoin Core picking up the other onion address? Can anyone help me?
