UPDATE: SORTED - Duplicate Sites in Website Dashboard

UPDATE: SORTED - was looking at wrong table, lol

I added a site manually.

Then installed the Piwik WP plugin on my site to insert the code.

Though because I am now running a multisite install, the plugin did everything for me (excellent) and registered the site for me.

Now I have the that site twice in the Website Dashboard.

How do I delete my orginal manually created one to avoid confusion?

Many thanks.
