This rarely happens, but Preview doesn't always show you 100% accuracy for your Published source code. Once you get pass the basic wikia code, Preview becomes less and less reliable.

You should play around in the Sandbox instead. You can safely test things there and Publish a bajillion times without worry. We usually experiment with templates and fancy new code in the Sandbox when we suspect Preview won't help.
