How to change "Marchi" (Manufacturers) in the top horizontal menu!

[nerosunero]

Hi there
At this page of our website
https://arte32.com/artisti/31-nerosunero
I would like to change from the Top Horizontal Menu 
the default text "Marchi" (Manufacturers) into "Artisti"
(see also the attachment here below)

In the Control Panel I tried all the options using the Translation tool
but I couldn't find a way to make the change!

I have also downloaded the entire website and searched it
but I couldn't come across to the word "Marchi" anywhere!
Therefore I couldn't change it!
Any help and tips more than welcome are usual!
Thank you
