web URL appears in posts

Hi guys.

Here is a strange one, and I think it may have something to do with buddypress – which has since been uninstalled and deleted from my website.

My website URL appears automatically below the headline on my posts [but not in posts created via RSS feeds].

See here: https://disclosure.co.nz/tea-pot-tape-key-banks-chat

Any ideas on why this is happening and how I can stop it?

Many thanks.
