You are constantly earning your influence power. It could be that the data you saw was about to update or did update (on the servers) but until you do something to update your browser, what you see stays the same. Then when you voted, it caused the browser to update and show the new information. Beyond that, one of the 2 places to see your power is only updated every hour, but I don't remember which one it is. All these tools are simply a way to get an idea of where you stand. I wouldn't get too hung up on the small differences.
