Thanks for the report. I took a look and your super dislikes are all saved correctly on your account, so this isn’t a case of them not sticking. They’re scoring the matching stories as hidden the way they should.
So the question is where you’re seeing them. A super disliked story gets marked hidden, but hidden stories still show up in a couple of spots by design. On the web they appear if you’re in All Stories, or if you’ve clicked the “show hidden stories” bar above the story list. Switch to Unread or Focus and they drop out. If you trained them while the feed was already open, reload the feed so the change takes effect.
On the iOS and Android apps, a story that was already loaded before you trained it won’t disappear on its own. Pull to refresh that feed so it rescores and they should go.
Which platform are you seeing this on? If it’s Unread or Focus on the web and they’re still there after a reload, tell me and I’ll dig in from there.
