I mean were do you see the name? On the site and when you are not logged in there are only 2 sources of your locale: browser's settings and ip.
If your ip is hidden by VPN then probably your browser language settings are different to UK.
If you are logged in then
BetFair should use your account settings first.
In MarketFeeder we use software language (en-GB for English version).
I've tried different VPN locations from Canada to Australia and never seen "Soccer"...
