Steps which reproduce the issue.

1. Using a query engine and metastore on a postgres database having default (public) schema.
2. Run the metastore task. All tables appear in left nav panel under Tables 'public' section.
3. Add to the metastore DenyList one or more tables to block access to. These are added with the schema (eg "public.table_1", "public.table_2").
4. Click Save on the metastore.
5. These tables are now correctly blocked when trying to query against them.
6. Public schema still shows all tables.
7. "Run" the task in the metastore.
8. The Public schema in the tables tab is now entirely gone.

Note: Removing all items from DenyList and re-running the metastore task brings back the public schema and tables.
