Need help with heist track xml

Did I do something wrong here? The heist track won't show up.
Here's the code:
<table name="XXXnomania">
<Localization directory="loc" default="en.txt"/>
<HeistMusic id="XXX" directory="sounds">
<event name="setup" source="stealth.ogg" start_source="stealth_start.ogg"/>
<event name="anticipation">
<source="buildup.ogg" weight="10"/>
<source="buildup2.ogg" weight="1"/>
</event>
<event name="assault">
<track source="assault.ogg" weight="10"/>
<track source="assault2.ogg" weight="1"/>
</event>
<event name="control">
<source="control.ogg" start_source="control_start.ogg" weight="10"/>
<source="control2.ogg" start_source="control2_start.ogg" weight="1"/>
</event>
</HeistMusic>

Instances of "<source" need to be called "<track source".
For example, "<source="buildup.ogg" weight="10"/>" should be "<track source="buildup.ogg" weight="10"/>".
