remove auto-complete entry in terminal new remote connection menu

Hello. I have been trying to delete the auto-complete (or maybe autofill or suggestion) entries in the dropdown menu in the remote connections management in the terminal app. However, I wasn't able to find out related information after much googling. The window in the screenshot above is shown after running the builtin terminal app in macos and opening the menu [S****]-[New Remote Connection].

I have tried using some combinations of fn, command, option, shift with delete including fn+shift+delete. I also tried removing some caches in the ~/Library/Cache . How could I delete these mistyped entries?
