RSS Feed, not updating

I am not sure where this question would be but I have an RSS feed. It is hosted on a website. Everything looks like when I open the RSS feed, no errors or anything, but It’s not updating. Its actually not even the same amount of items listed between the dashboard and the UCP. The dashboard has 6 items, the UCP has 5, but the RSS Feed itself has 7. It’s almost like there is some limit that i am not aware of or something. Any help would be great, thanks guys!
