Kathi,
I'm sorry you are having problems. If the settings are correct and your site is supplying the increased number of stories then this may be a caching issue.
Zinepal uses caching for speed and therefore you may need to clear the cache. The cache will refresh automatically after a length of time but you can also clear it by changing the feed-type and then resetting it back to the previous state. For information on how to do this please read FAQ No.6. under "Help->Frequently Asked Questions".
I hope this helps to resolve your problems.
Best regards, Paul.
