Siblings get unburied on syncing with AnkiDroid

I looked at this setting in AnkiDroid and found it was set to 23 (!) hours past midnight

If this was causing this problem, Anki sync should synchronize this setting between devices to avoid this kind of problem in the future.

Yes, at the moment it does not sync this setting either way.
