I've attached two epubs.

The first attached epub has two fonts that are using Adobe obfuscation. If calibre updates the metadata, the <dc:identifier opf:scheme="UUID">urn:uuid:ef424b40-3f28-4fc6-ba08-2930290145bc</dc:identifier> line is removed from content.opf and the fonts are unusable.

The second attached epub with polished in it's name is the result of running Polish with update metadata ticked which removes the dc:identifier line.
