If you use third-party plugins like filter plugin then don’t forget about this plugin translation http://prntscr.com/rhalij And if you find any WooCommerce strings missing just check if it’s transalted in WooCommerce files http://prntscr.com/rhano3 Because it’s missing as I can see.
We are theme developers and we are not responsible for third-party plugins translation, only for theme and XStore Core.
