Thread:Extension talk:Semantic Watchlist/Semantic Watchlist not detecting changes

I've set up a property, and a watchgroup for values of that property, and I'm watching the property. However, when I change it, I get no messages and, when I go to the page title=Special:SemanticWatchlist it always says:

''You have no items on your semantic watchlist."

I'm not sure if it's connected, but, on this site, the mediawiki site, my preferences show:

But on my wiki I only see the options:
