There could be several things that may cause this.

This can be cause by the browser using a cache from it's stores even though you have told it not to. They Update Views is that instead of waiting and doing a once every hour or so, it will add to the "Times Viewed" immediately.

This would most likely be a topic that the vBulletin Support team would help with. Posting at vB.com would give you the best results, unless they sent you here to ask it.
