Merge tag bug when using pre render

Hello,

I've noticed a bug with merge tags - not sure if you are aware or if someone can explain why this is not woking as it should.

I have a radio field labelled 'Item' with the field id 19

Usually to ouput this data as merge tags I would simply do this...

choice text {Item:19}
choice value {Item:19:value}

Simples. The above merge tags work.

But when using pre-render php, for example...

$products = get_field('item_information',$post->ID);
$items = array();
foreach($products as $product)
	$items[] = array(
		"text" => $product['order_description'],
		"value" => $product['price_euro']
	);
foreach($form["fields"] as &$field){
    if($field["id"] == 19 ){
        $field["choices"] = $items;
        $field["label"] = get_the_title($post->ID);
    }
}
return $form;

If I then use these merge tags...

choice text {Item:19}
choice value {Item:19:value}

They both output the value. Which is incorrect because the choice text should not the choice value.

Any ideas why this behaviour happens?

Thanks

Cool thanks Chris.

Be interesting to see what they say.
