Hello, I noticed a translation error into Russian in the files:

...components/com_easystore/layouts/checkout/customer-note.php line 17 COM_EASYSTORE_ORDER_FIELD_CUSTOMER_NOTE="Customer Note"

<div class="easystore-checkout-customer-note">
    <textarea class="form-control" name="customer_note" rows="3" placeholder="Customer Note"></textarea>
</div>

...components/com_easystore/layouts/checkout/information.php line 145 COM_EASYSTORE_CHECKOUT_SHIPPING_ZIP_CODE="Zip Code"

<div class="easystore-half-width">
                    <input name="billing_zip_code" type="text" class="form-control" placeholder="ex. 1100" x-model="information.billing_address.zip_code" />
                </div>

I attach a screenshot: https://disk.yandex.ru/i/B8hyMpNqipKgcg Please fix it in the next release.
