Analytics Id Issue

Hello.
I appear to have an old GA Id in the source code of my site but the new/correct one in my GA account, on my WPD settings page and also on the settings of the plugin itself when I log in to Wordpress.org.
Any idea why the site/source code isn't updating or what I can do to fix the issue?
(The reason I have an old and new GA Id is to do with the URLs not matching initially so I deleted the original profile in GA and started again).
Kind regards,
Paul
