indeed, there's an additional predicate missing:
<xsl:copy-of select="$uh2[not(AttributeName=preceding::*[CodeId='30DAYPM']/AttributeName)]"/>

btw, here you have a sample using the Muenchian technique:

<xsl:key name="recordByC" match="Record" use="CodeId"/>
<xsl:key name="recordByCA" match="Record" use="concat(CodeId,AttributeName)"/>

<xsl:template match="/">
	<xsl:variable name="uh2" select="key('recordByC','30DAYPM')"/>
	<xsl:element name="Copy">
		<xsl:copy-of select="$uh2"/>
	</xsl:element>
	<xsl:element name="Filter">
		<xsl:copy-of select="$uh2[generate-id()=generate-id(key('recordByCA',concat('30DAYPM',AttributeName))[1])]"/>
	</xsl:element>
</xsl:template>
