Name change of Additional Info is not showing

Before I installed the extension I had changed the name of the Additional Info title for the extra fields to Technical Information. I've since noticed that it has changed back to Additional Info. Is this due to MEFGforK2? And if so how can I get it to change back?
The problem can be seen at yokosphotoworld.com/development/stonecir...389-verde-tropical-g
Thanks

Hello Madeleine,

MEFG does not override the item template file, this change can be done with a template override, or it maybe hardcoded in the item.php template override.

No, I've tried over riding it, it's not worked and it's not hard coded in to the template, at least not as far as I or the people on the K2 forum can see. But thanks anyway.

Did you install another K2 plugins like multiple images?
I'm asking because some plugins have their own overrides in the plugin folder, to find it out, try to disable the plugins one by one and check.

Yes, it's the filter that's doing it - thanks
