Unusual Template Behavior with XSL - xslt

Question

Experiencing some very odd behavior with, what should be, a very simple use of XSL and XSLT.
Here's a code sample.
<xsl:template match="check">
<div class="check">
<xsl:apply-templates mode="check">
<xsl:with-param name="checkName">testVariable</xsl:with-param>
</xsl:apple-templates>
</div>
</xsl:template>
The template called above
<xsl:template match="option" mode="check">
<xsl:param name="checkName" />
<div class="option">
<input type="checkbox">
</input>
<label>
testText
</label>
</div>
</xsl:template>
Pretty simple right?
It should, for each instance of a instance in the XML create a checkbox in a with a hard coded label.
However, what I'm getting is
<div class="check"></div>
<div class="option>Checkbox stuff here</div>
<div class="option>Checkbox stuff here</div>
<div class="option>Checkbox stuff here</div>
<div class="option>Checkbox stuff here</div>
<div class="check"></div>
<div class="option>Checkbox stuff here</div>
<div class="option>Checkbox stuff here</div>
<div class="option>Checkbox stuff here</div>
<div class="option>Checkbox stuff here</div>
Here's some sample XML
<check><option key="1"/><option key="0"/><option
key="0"/><option key="0"/><option
key="0"/></check>
Anyone know what's going on? :D

The problem is either in the XML-document/code you haven't shown to us or, less likely, you may be using a buggy XSLT processor.
This transformation (Your code wrapped within an <xsl:stylesheet>):
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="check">
<div class="check">
<xsl:apply-templates mode="check">
<xsl:with-param name="checkName">testVariable</xsl:with-param>
</xsl:apply-templates>
</div>
</xsl:template>
<xsl:template match="option" mode="check">
<xsl:param name="checkName" />
<div class="option">
<input type="checkbox"></input>
<label>testText</label>
</div>
</xsl:template>
</xsl:stylesheet>
when applied on the provided XML document:
<check>
<option key="1"/>
<option key="0"/>
<option key="0"/>
<option key="0"/>
<option key="0"/>
</check>
produces the wanted, correct result:
<div class="check">
<div class="option">
<input type="checkbox"></input>
<label>testText</label>
</div>
<div class="option">
<input type="checkbox"></input>
<label>testText</label>
</div>
<div class="option">
<input type="checkbox"></input>
<label>testText</label>
</div>
<div class="option">
<input type="checkbox"></input>
<label>testText</label>
</div>
<div class="option">
<input type="checkbox"></input>
<label>testText</label>
</div>
</div>
I have verified that the transformation produces identical results when run with:
Saxon 6.5.4
MSXML3, MSXML4, MSXML6
.NET XslCompiledTransform and XslTransform
Saxon 9.1.05
AltovaXML (XML-SPY)
XQSharp
