Articles are not showing up in Focus

All weekend, I have noticed that articles are not showing up in my Focus list, other then from a single source (Lifehacker), If I switch to Unread, and say look at my (The Verge) feed, I see I have unread articles that are labeled with the green focus dot, yet they are only found in unread and not in my focus list.


Update: I ran the intelligence trainer, and just clicked “save & next” until completion, and it brought all articles that are focus, back into Focus.
