fix extra_options_section misbehaving when there's just one extra_options element

                                self.infotext_fields.append((comp, setting_infotext_name))

        def get_settings_values():

            return [ui_settings.get_value_for_setting(key) for key in self.setting_names]

            res = [ui_settings.get_value_for_setting(key) for key in self.setting_names]

            return res[0] if len(res) == 1 else res

        interface.load(fn=get_settings_values, inputs=[], outputs=self.comps, queue=False, show_progress=False)
