Can't change "Postcode / ZIP" field label in woocommerce
<p>I have a site in hebrew based on woocommerce. The translation working great, however, the field &quot;Postcode / ZIP&quot; is refuse to be trasnlate:</p>
<p><a href="https://i.stack.imgur.com/ybQV1.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ybQV1.jpg" alt="enter image description here" /></a></p>
<p>I've tried to change it using this code:</p>
<pre><code>add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );
function custom_override_checkout_fields( $fields ) {

    $fields['billing']['billing_postcode']['label'] = 'test';

    return $fields;
}
</code></pre>
<p>But something weird happen: when I reload the page I can see the change take effect, but after a second it change back to &quot;Postcode / ZIP&quot;.
Another weird thing: the above script work for the other fields, something is wrong with that specific field.</p>
<p>Anyone know what's going on?</p>
<p>Thanks!</p>
