We are setting up a voting page with many like buttons (www.real-leaders.com/vision100) with a VIP account.

We have tested it on various machines and browsers, and on many, after refreshing the page once you've voted, some of your votes disappear/reset to no vote, or the results don't update on other machines, and in one instance all the like buttons defaulted to 3.

Is there any other settings I need to check?
