In Redash version 8.0.0+b32245, in the PostgreSQL database:

queries table (query table)
dashboards table (dashboard table)

The two fields is_archived (whether archived) and is_draft (whether draft) — are these fields automatically updated by the system?
Why is it that these items can no longer be found/searched in the Redash web interface, but they still exist in the database (SQL source data), and both fields are set to 'f' (false)?
Additionally, when querying by excluding items where data_source_id is empty, and even after joining the dashboards table with the query_results table to filter out records with empty data_source_id, some dashboards still have is_archived = 'f' and is_draft = 'f', but they still cannot be found in the UI. What is the reason for this?
