Magento – Import/Export CMS Pages / CMS Blocks

Seems, this is expected behavior by design. Please, look at customer address backend model:

class Mage_Customer_Model_Resource_Address_Attribute_Backend_Street
    extends Mage_Eav_Model_Entity_Attribute_Backend_Abstract
{
    /**
     * Prepare object for save
     *
     * @param Varien_Object $object
     * @return Mage_Customer_Model_Resource_Address_Attribute_Backend_Street
     */
    public function beforeSave($object)
    {
        $street = $object->getStreet(-1);
        if ($street) {
            $object->implodeStreetAddress();
        }
        return $this;
    }
}

And Mage_Customer_Model_Address_Abstract

/**
 * set address street informa
 *
 * @param unknown_type $street
 * @return unknown
 */
public function setStreet($street)
{
    if (is_array($street)) {
        $street = trim(implode("\n", $street));
    }
    $this->setData('street', $street);
    return $this;
}


/**
 * To be used when processing _POST
 */
public function implodeStreetAddress()
{
    $this->setStreet($this->getData('street'));
    return $this;
}

Since Module ImportExport uses attribute's backend models, so this is expected behavior.

As far as I know you can't use one CMS page for different store views in Magento. Instead you should have different CMS pages for each store view.

And unfortunately it's not possible to duplicate CMS pages in Magento. But there are bunch of extensions which can do the job for you. Below are some of those extensions.

Hope this helps.
