Autoposts posting multiple times

I have a license and we are having a problem with the autoposting on Twitter. We have it set to autopost ever .15 hours and loop any posts less than a day old. However, when it does post it posts the same post more than once at the same time. Any ideas? Our Twitter users are getting frustrated seeing three of the same post appear all at once in their timeline.
