Hello,
1) Add the following code to the custom CSS to hide that text because there is no special option for this
.category-grid .categories-mask .count {
display: none;
}
2) Use XStore theme and XStore core plugin translation files https://xstore.helpscoutdocs.com/article/30-base-theme-translation
Make sure that both translations are up to date https://xstore.helpscoutdocs.com/article/103-translation-files-update
