remove or rename "product catagory"?

I have linked the "Product Category" option in HikaShop as a page in the menu system. But I can't figure out how to rename or remove the title "Product Catagory" at the top. Help?

Go in the menu Products->Categories. Click on root on the right explorer. Edit the "product category" category.

Thank you!

...and what can i do if i don't want any title on that page ?
Thank You

You can:
1. empty the name of the category.
2. Or turn off the show title option of your menu in the joomla options of your menu.
