Google (G4) analytics code | WordPress.org

I installed my Google (G4) analytics code yesterday, it showed up in the Coming Soon preview window in top left corner. I have noticed another post on here I edited the plugin as per that post:
‘google_al’ => $_POST[‘google_al’],

The code is still displaying after making the change..

It is the one function that is stopping my from upgrading to Pro
