How do you change where the links point in the studio themes buddypress dropdown section?

The forums section in the drop down menu is pointing to the wrong location.
I have updated the buddypress pages section and
the rest of the references to the forums behave correctly.

I also have a menu button: http://joininghands.org.uk/joininghands-forum
that works fine. So it's just a case of updating this errant entry.
which insists on pointing to: http://joininghands.org.uk/forums/
I believe this was the default before I changed it so it seems that this setting hasn't updated.

It would also be cool to know how to change these settings more generally if possible, for future reference.
I don't mind if it means going into the database to change a setting etc .

Thanks in anticipation , Warren
