Category links not responding

I’ve set the bookmark feature up to allow users to create categories to store favourite posts in. When I go to the bookmark page, the categories don’t respond when clicked – only the “All Bookmarks” posts show.

If I right click and select “open in a new tab” the page with the categrory-specific boookmarks open just fine.

Any assistance on how I can make the links responsive?
