The Auto-cycle option appears to get stuck.
Using google chrome and your first demo
Auto cycle appears to work initially and images are automatically presented as expected. However if you switch Auto-cycle off then back on again without reloading the page it updates just once and then stops updating.
Using the Navigate options appears to work similar and also only updates once.
If the entire page is reloaded the autocycle option again works until the options are manually updated via the UI then same issue returns.
