Getting multiple posts of same article

Hi,

I have the latest version of your plugin installed and I read your FAQ but my problem isn’t listed.

The plugin has been autoposting the same article multiple times, at least 3 reposts of same articles and often 12 posts for the same article. See http://tinypic.com/r/1z23klf/8

I changed the Settings to fetch 1 post per 15 minutes and total of 15 posts. Could you look into this problem?
