Can't Change Nav Link

URGENT PLEASE! (need to go live today!) I want to change the SHOP nav link from ‘‘KoronaGadget’’ to now point to ‘‘Shop Front’’. It’s normally simple but it just isn’t working, it keeps going back to KoronaGadget, even if you type in /shop. There was a 301 which I have deleted. Share link below plus live site.

Here is my site Read-Only:
(how to share your site Read-Only link)

I don’t get it. The nav link “shop” goes to Shop Front Sweetnam & Bradley
Please eleborate.

How odd - my machine must have done something cached, as you are quite right it is working on my other ones! Thank you @Yatsuba
