The “Show Count” to display only count in specific category

There are only 2 products under the Classic Handles category

…but the count for Right Hand Opening shows (3) which is the total number of products in shop which does not make sense for those who are only looking for products in the Classic Handle category page which will only display 2 products for the category when the filter says 3

(in the future, count will be more confusing when there are more products added in other categories.)

How do I set the count to only display filtered products in a specific category?

These are for attribute filters
