I replaced my "Home" menu item to go straight to K2 and I used the category view and selected two categories to show (each categories has 3 sub-categories). I changed the Item ordering in the parameters to show most recent first. (I'm using this to replace the standard Joomla Frontpage)

I have two articles that were created on the following dates
Monday, 27 July 2009 21:43
Sunday, 21 June 2009 17:11

And a third article created Thursday, 04 June 2009 09:27

When I clear the cache in the Administrator panel and I view my site the articles show up in the correct order. Afterward if I leave my site and come back to it 30 minutes later or so and refresh the page; The first two articles don't show up at all and the third article appears at the top of the page. I then go back to the Administrator panel and purge the cache and then the everything goes back to normal again for a while.

I was using xcache for my file handler and thought that could be the problem so I switched to file caching instead but the problem still happens.

Anyone else see this type of problem?
