How to Remove 'All' Category on Bedford Template in Version 7.0

Site URL: https://www.waypointtech.com/

Hello,

We are trying to hide the 'All' category from our sales pages but cannot figure out how to do so. 

We've tried using other CSS changes recommended on other threads but none of them seemed to help out. 

Any help on this would be greatly appreciated!

Add to Design > Custom CSS

li.active-link.all {
    display: none;
}

Thanks! This worked to remove the All category but as soon as I go to any other category on our page, this All category reappears. Is there a way to remove it from ever showing up on any page?

@tuanphan Is there a way to make the change you suggested above, apply to all pages a customer can view? If I go to any other category, this All category reappears.
