Feed item nodes are recreated everytime when cron runs

I am using this feed (http://semweb.meetup.com/events/upcoming/atom/) with a custom content type i created that has a cck date field. Since the RSS does not have the date as an attribute i am trying to have the feed pull in the feed items as unpublished so that i can go through an approval process for these feed items. This would allow me to add in the date field manually before it gets published to my site. Problem is that everytime i run cron ( when it actually runs ) i see the message on the status page indicating my aliases for these feed items have been created ( which would have already been created before when i created the feed and refreshed it ). The result is that my manually published feed items are all gone and i have new feed items that are unpublished and of course lost my manually set cck date field.

I thought perhaps it was because i was pulling in the feed items as unpublished and editing them ( adding my cck date field) before manually publishing it so i tried changing my feed item content type to published so that all the feed items would come in in a published state and THEN i would update it... but i have the same problem... it deletes all my previous nodes.

Im using feedAPI 6.15, feed element mapper 6.x-1.0-beta4 , and drupal 6.9. I should mention that i had an issue with running cron with the date field on my custom feed item type which i by applying the patch located at http://drupal.org/node/215979 ....
