How to locate and customize the Manufacturers Page

[nerosunero]

Hi there
I would like to change the text "I nostri arstiti" that shows on the top of this page
https://arte32.com/artisti (see attachment)
This is the page listing all the Brands (also known as either Manufacturers or Marchi) (in my case they are Artists)
However I can't locate it, ie: https://arte32.com/artisti anywhere either on the Control Panel or inside the website directory!

I downloaded the entire website and searched for
""I nostri arstiti" (that is the bit of text I want to change)!
I found that entry in one instance only, inside this xml file:
/www/themes/at_movic/samples/leobootstrapmenu.xml

I opened the leobootstrapmenu.xml file and changed  "I Nostri Artisti" into "Artisti" 
but (as I was suspecting) to no effect at all!

Any help would be more than welcome!

thanks in advance
