Issue is not related to our theme but to WooCommerce plugin and their option “Hide out of stock items from the catalog”. If this option is enabled then WooCommerce does not count products well, we have enabled the default Store front theme to show you https://gyazo.com/6462d6775d1d92b85cbffdf8e7351c9e
So, contact WooCommerce plugin support to get help with this issue https://wordpress.org/support/plugin/woocommerce/
I see that somebody already contacted them with the same issue https://github.com/woocommerce/woocommerce/issues/22986
