I believe the problem is in this line:
<xsl:copy-of
select="(key('step',string-join(ancestor-or-self::*[@ID]/@ID,',')),.)[1]"/>

The section reading
'(key('step',string-join(ancestor-or-self::*[@ID]/@ID,',')),.)' will
select all matching Rate_Event nodes correctly, as well as the current
node. The predicate at the end '[1]', will then take the first item in
this list. I suspect you want to use some kind of conditional here...
