I'm not sure if this is the right answer, but when I'm browsing around at times I cast some votes then go back to a section I'd previously visited and the XP nodelet says I've still got all my votes. Usually this is do to the browser keeping a cached copy of the page in memory. I just hit refresh and then it'll show the correct vote number.
