Due Date of cards not being rescheduled appropriately if studied in a filtered deck (despite proper deck options)

Hi all,

I’m having an issue with filtered decks and due dates. If I have some extra time, I’ll study some cards due the next day (or two) AND have not been reviewed within the last few days. I create a filtered deck for these cards and made sure to enable the “reschedule cards based on my answers in this deck” option (screenshot below).

However, I’ve noticed that quite often, there will be several cards here and there whose due dates are not being appropriately rescheduled. I’ve attached a screenshot of the card info of one such card.

You’ll see that it was reviewed in a filtered deck on 12/24/2025 and given an interval of 11 days, which means it would be due on 1/4/2025. I studied it one day ahead of schedule on 1/3/2026 (as shown below), and it was given an interval of 21 days. However, today (1/4/2026) this card came up for review (against my expectations)

Interestingly, in the card browser, the interval for the card still displays “11 days”. Also, if I try to manually set the due date and interval of this card to 21 days (Ctrl + Alt + D → 21!), the interval now becomes 1.1. months, for some reason. Actually, whether or not I include the !, the interval becomes 1.1 months.

I’m using FSRS. I also nest the filtered deck(s) under a “normal” deck (to ensure reviewing follows my deck options, namely showing review cards before new cards), like so:

I study by selecting the “normal” deck instead of the filtered deck.

Interestingly, I just ran a quick test in which I created a filtered deck of review cards only (no l earning cards), and regardless of whether I selected the normal or filtered deck to study, the card info interface shows “Review” instead of “Filtered” under the “Type” column.

Would anyone happen to know what is going on? Thanks all.

TL;DR: despite enabling “reschedule cards based on this deck” option for a filtered deck, cards reviewed in filtered deck are occasionally not being scheduled properly

That actually looks like a sync conflict. If you (or your add-ons) make changes on one device while you also have unsynced changes on another device, it can leave cards in an inconsistent state like this – both studied and not studied. See this prior post for causes/solutions: Scheduling differences between Anki desktop and Android - #4 by Danika_Dakika .

Since you’re using FSRS, there’s no need for you to change the interval as well – in fact, FSRS controls that.

Thanks so much for your reply and the suggestions. I’ll def give them a try.

I always though I was fastidious about syncing, but it never occurred to me to sync before making any changes.
