In case if a discovered LLD rule is no longer discovered and is marked as a lost resource, and a user manually enabled and then disabled it, this LLD rule is still marked for automatic deletion by LLD after the time period that is set in the parent LLD rule configuration form.
This behavior differs from the one observed for items and triggers - these entities, when manually disabled, are excluded from automatic deletion by LLD (introduced in ZBXNEXT-2020). Also the message in the inco column changes accordingly (specifically mentiones that this entity will not be automatically deleted).

Please exclude manually disabled LLD rules from automatic deletion by LLD in the same way as it is currently done for items and triggers.
