Hello,
You are using “Alternative” category style for your categories.
Screenshot: https://jmp.sh/hQ2HLkb

You can check that the picture and the product counter is clickable and leads to that specific category page. Only the category title is not clickable and just readable in “Alternative” style.
So you can use any other category style like “Center Title” or “Replace Title” or “Default” from theme settings >> Shop >> CATEGORIES STYLES. So the thumbnail contains the product title and other info and the whole thumbnail is clickable.
Best Regards.
