Could you share your collection with me to reproduce this error?

By the way, does it also happen when you disperse all siblings manually?

[szalejot]

Here is the collection without media: https://drive.google.com/file/d/1KNX9rG0OeqpoEAe1HjLqFF3qKZgMlBBq/view?usp=sharing

When I try to disperse all siblings manually I get this error. I tried 3 times and it failed every time.

I find out the problem: some cards' due date is earlier than the last review date. Do you know why?

[L-M-Sherlock]

I recommend rescheduling all your cards. It will fix the problem.

[szalejot]

That's strange, but I have no idea. I haven't modified Anki database directly. The only add-on that modifies due dates I have is FSRS Helper. At some point I have exported this deck, deleted it from Anki and then imported again after a few days. But it shouldn't matter.

Seems like rescheduling all your cards fixed the issue. Thank you for your support.
