I see that you edit the parent theme. It’s a bad idea because you won’t be able to update theme to the latest version or lose changes after theme update.
Also, don’t change the text domain in parent theme style.css https://prnt.sc/yq3zaj if you don’t change text domain in all the theme files, https://prnt.sc/yq3p8j
I got back the xstore text-domain, created translation file, translated mentioned string and it works https://prnt.sc/yq4891
