unlist mark lost after Export/Import

[ArtemKuchin]

I needed to transfer the post from one site to another keeping the unlisted mark, but the marks gets lost during export/import! I've looked at the xml file and it does not have any specific meta field for unlink mark, However, if a post is marked for unlisting it has 3 identical meta fields:

	<wp:meta_key><![CDATA[_encloseme]]></wp:meta_key>
	<wp:meta_value><![CDATA[1]]></wp:meta_value>
	</wp:postmeta>

Strange that it has 3, but that still does not help. It just says that enclosure process has not run on it yet.
Need a way to export/import unlisted mark.

Hmm, just installed the post meta data viewer pluging and it does not show any meta data for unlisted post. How so?
