Categories & Tags Display in Store Pages | All Products Showing

Dear all,

Hope my message finds you well and safe. I really need one more help with Category/Tag display in Store Pages. 

As you can see in the attached screenshots, I have 4 sub-categories under Accessories. When I want to display individual categories through links I have done the way in the screen shot.  And the link as follow - 

https://www.banyancanopy.com/shop-accessories/technology

However, when I click on the Link the "Technology" products show up first but it is followed by rest of the 127 products I have in the main store page. As you can see in the second screenshot, the Phone Cases are shown first but it is followed by Notebooks, Stickers, etc. 

How can I do it to change this so that when someone click on Technology Link, only products under Technology Category/Tag will be displayed in the Store page. 

Thank you so much in advance. 

David
