@melosconti: When you use POEDIT to translate the file using the catch-store.pot file in the languages folder and you can find text item and items and translate but the words are not showing up when you search for it using the Loco Translate plugin.
If you would like to change the text item and items in the theme file, firstly I suggest you to create a child theme. If you do not know how to create a child theme you can use Generate Child Theme Plugin.
Then Go to => Child Theme folder => functions.php and add the following Code.
function catch_store_cart_link() {
?>
<a class="site-cart-contents" href="<?php echo esc_url( wc_get_cart_url() ); ?>" title="<?php esc_attr_e( 'View your shopping cart', 'catch-store' ); ?>">
<?php echo catch_store_get_svg( array( 'icon' => 'shopping-bag', 'title' => esc_html__( 'View your shopping cart', 'catch-store' ) ) ); ?>
<?php /* translators: number of items in the mini cart. */ ?>
<span class="count"><?php echo wp_kses_data( sprintf( _n( '%d item', '%d items', WC()->cart->get_cart_contents_count(), 'catch-store' ), WC()->cart->get_cart_contents_count() ) );?></span><span class="sep"> / </span><span class="amount"><?php echo wp_kses_data( WC()->cart->get_cart_subtotal() ); ?></span>
</a>
<?php
}
Now find item and items and replace it with your translated text.
Let me know if this helps you out!
Kind Regards,
