TMNR on "[Polylang] Touchfolio theme localization"

Hi,
I have successfully localized everything I need, except for the menu button name that appears when responsive design kicks in past 600px. I have found "menu" in .po file and changed it to my liking (like other entries, which worked flawlessly), but it does not change when switching languages. This is the only remaining issue and I've spent numerous hours trying to find how to do it. It's driving me mad. Please help.
