Hello, @Ale,
1- Sorry to say, that there is no option in the theme nor there is any widget available like this on the shop page you cannot make it as it appears on the single product page except for customization.
2- In order to solve your issue simply go to the Dashboard >> XStore >> Theme OPtions >> Theme Custom CSS >> Global and paste the below code at the bottom of the CSS box there.
.woocommerce-shop .product-category:first-child{display:none !important;}
Then save settings and check back to your site after clearing the browser cache.
