make sure all things are translated

[shoulders]

I have found some things are not translated i.e.

<?php
	echo "<h3>After display title:</h3>";
	echo $this->item->afterDisplayTitle;
	echo "<h3>Before display content:</h3>";
	echo $this->item->beforeDisplayContent;
	echo "<h3>After display content:</h3>";
	echo $this->item->afterDisplayContent;
	
	JLoader::register('FieldsHelper', JPATH_ADMINISTRATOR . '/components/com_fields/helpers/fields.php');
    $fields = FieldsHelper::getFields('com_helloworld.helloworld', $this->item, true);
	echo "<h3>Fields set to not display automatically:</h3>";
	foreach ($fields as $field)
	{
		if ($field->params->get("display") == "0")
		{
			echo FieldsHelper::render($field->context, 'field.render', array('field' => $field)); 
			echo "<br>";
		}
	}
?>
