Look at bp-core-settings.php in the bp_core_screen_general_settings() function. It is the line that begins

add_action( ‘bp_template_title….

which sets the title. It calls the bp_core_screen_general_settings_title() function which returns the title. Two options – create a custom language file and translate the title there, or figure out where/how to remove_action that line.
