XSL double xml element - xslt

Question

I hope somebody can tell me why I do get 2 E1EDT20 elements in my result? Must be doing a copy too many but I can't figure it out.
My input xml
<SHPMNT05>
<IDOC BEGIN="1">
<EDI_DC40 SEGMENT="1">
<TABNAM>EDI_DC40</TABNAM>
</EDI_DC40>
<E1EDT20 SEGMENT="1">
<TKNUM>0000287214</TKNUM>
<E1EDL20 SEGMENT="1">
<VBELN>0081018702</VBELN>
<ABLAD>1</ABLAD>
<VSTEL>EWM</VSTEL>
<VKORG>0100</VKORG>
</E1EDL20>
<E1EDL20 SEGMENT="1">
<VBELN>0081018703</VBELN>
<ABLAD>1</ABLAD>
<VSTEL>EWM</VSTEL>
<VKORG>0210</VKORG>
</E1EDL20>
</E1EDT20>
</IDOC>
</SHPMNT05>
My XSL
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="E1EDT20">
<xsl:copy>
<xsl:copy-of select="*[not(self::E1EDL20)]"/>
<xsl:copy>
<xsl:for-each-group select="E1EDL20" group-adjacent="concat(ABLAD, '|', VKORG)" >
<CMR>
<xsl:copy-of select="current-group()"/>
</CMR>
</xsl:for-each-group>
</xsl:copy>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
My current result looks like:
<SHPMNT05>
<IDOC BEGIN="1">
<EDI_DC40 SEGMENT="1">
<TABNAM>EDI_DC40</TABNAM>
</EDI_DC40>
<E1EDT20>
<TKNUM>0000287214</TKNUM>
<E1EDT20>
<CMR>
<E1EDL20 SEGMENT="1">
<VBELN>0081018702</VBELN>
<ABLAD>1</ABLAD>
<VSTEL>EWM</VSTEL>
<VKORG>0100</VKORG>
</E1EDL20>
</CMR>
<CMR>
<E1EDL20 SEGMENT="1">

<ABLAD>1</ABLAD>
<VSTEL>EWM</VSTEL>
<VKORG>0210</VKORG>
</E1EDL20>
</CMR>
</E1EDT20>
</E1EDT20>
</IDOC>
</SHPMNT05>
Required result

Well, as you say, you have two xsl:copy:
<xsl:template match="E1EDT20">
<xsl:copy>
<xsl:copy-of select="*[not(self::E1EDL20)]"/>
<xsl:copy>
