Some illagers won't join raid even if their nbt tag CanJoinRaid is true

Those two illagers were the remain of last raid,which ended abnormally for being too long after its starting.I think this might be the reason–they still thinking they belong to the previous raid,and refuse to join the later one.However,they won't behave like they are in raid–the witch never throw regeneration potions to that pillager again.
