Read articles re-added each Flym Update

[Saijin-Naib]

Every Flym update, all the most recent articles from two sources are re-added as New/Unread, despite both retention period being one day for Read items, and the items having been marked Read more than a day prior.

So far, I only observe this behavior with two sources on my feed.
