kaxil opened a new issue #8720: URL: https://github.com/apache/airflow/issues/8720
**Apache Airflow version**: 1.10.10 **To Reproduce** Steps to reproduce the behavior: 1. Create new directory and use `astro dev init` 1. Change the FROM line in Dockerfile to `FROM astronomerio/ap-airflow:1.10.10.dev-buster-onbuild-8091` 1. Enable DAG Serialization (Put `AIRFLOW__CORE__STORE_SERIALIZED_DAGS=True` in `.env` file in the project folder) 1. `astro dev start`. Once the Webserver boots up, run any DAG 1. Once the DAG completes execution, click on the task that has few upstream tasks in Graph View 1. One the **Task Instance Modal**, select **Upstream** -> click on **Clear**. You will see a list of tasks but that would not have all the upstream tasks. **Screenshots**  ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
