openlayers, views and gpx

Hi Group

I hope this is the right place to post this question.
Or should i post in views gruop ?

I followed this toturial :
https://drupal.org/comment/reply/1481374#comment-form

I use this for showing gpx tracks.
The problem is, that i upload more than one gpx in one node.
In views and OL output, only one track is shown, no matter how many tracks i upload to the node.

Can anyone tell me what i am missing in views to show all tracks ?
Thanks a lot.
