Unsubsribe link produces two URLs, not one

Hello. phplist v3.6.15

When creating an unsubsribe link I’m using the URL:

Hovering over the link in the email shows:

Yet, when it goes to the PHPlist website there is an error and the link gets transformed into:

If you remove the https://xxxx.com/lists/admin/ from your URL, as you don’t want to be directing users to your admin side of things, you should be able to use the simple [UNSUBSCRIBEURL] as that creates the personalised unsub link people need.

yeah I just figured that out. Duh.

Thank you have a great day.
