Route:
No nothing is going on there, it is only that in your orignal GPX file it has:
<rtept lat="36.366570" lon="-116.704730">
<name>110</name>
<cmt>DEATH VALLEY</cmt>
<desc>DEATH VALLEY</desc>
<link href="http://www.travelbygps.com/guides/deathvalley/deathvalley.php">
<type>text/html</type>
</link>
<sym>Waypoint</sym>
<type>Waypoint</type>
For my <rtept/> transforms I had the desc, cmt and symb transdformed to the <description/> element. So it went according to the rules. The only thing I chould have done is to add spaces and captions like Symbol: Waypoint, Comment: Death Valley,.
As I wrote before the Sheet is in draft and for the time being i mopped most content elements into the desdcription element.
