It looks like you have caching in place – via a plugin called Hummingbird – so I suspect that may be the cause of this (ie, you’re viewing cached content).
If you disable that plugin/turn off caching, is the problem resolved? It may be possible to keep caching enabled and set up exceptions for various page elements, but you would need to work alongside the author/support team of that other plugin to figure out how (or perhaps you could simply adjust the settings, so the cache is refreshed at more regular intervals).
Does that help at all?
