Invalid DAG count is shown on Airflow UI when zero DAGs are present #34100

Apache Airflow version

2.7.0

What happened

When Example DAGs are disabled from using docker-compose.yaml file, and no DAGs are present in the dags folder, its still showing the DAG count of Example dags on screen as 53 ( No DAGs are present on UI)

What you think should happen instead

• After updating value for parameter AIRFLOW__CORE__LOAD_EXAMPLES to false, its removing all DAGs from UI
• DAG Count should also get updated to zero(0)

How to reproduce

• Download 2.7.0 docker compose file available at ('https://airflow.apache.org/docs/apache-airflow/2.7.0/docker-compose.yaml')
• Create folder structure using data available here
• Create an airflow deployment using above mentioned steps
• Initialize Airflow using docker compose up airflow-init
• Start Airflow application using docker compose up command
• Airflow started with 53 Example dags
• DAG count still shows 53
• Stop Airflow application using docker compose down command
• Updated parameter AIRFLOW__CORE__LOAD_EXAMPLES: 'true' to AIRFLOW__CORE__LOAD_EXAMPLES: 'false' in docker-compose.yaml file
• Start Airflow application using docker compose up command
• Airflow started with zero(0) Example dags
• DAG count still shows 53 but no DAGs are there on the screen
