edwardwang888 opened a new issue #16824: URL: https://github.com/apache/airflow/issues/16824
**Apache Airflow version**: 2.1.1 **Environment**: Docker setup from Installation page - **Cloud provider or hardware configuration**: - **OS** (e.g. from /etc/os-release): Mac OS 11.4 - **Kernel** (e.g. `uname -a`): - **Install tools**: Docker - **Others**: **What happened**: After adding new tasks to an existing DAG, the newly added tasks appear as task instances in existing DAG runs with `no_status`. These usually appear as a white box with a black border. However, after attempting to mark these task instances as success/failed in the UI, and then cancelling at the confirmation screen, the black border disappears. <!-- (please include exact error messages if you can) --> **What you expected to happen**: Black border should remain. **How to reproduce it**: 1. Create DAG with at least one DAG run.  2. Add new tasks to the DAG.  3. Attempt to mark the newly added task instances as success/failed, but click `Cancel` upon reaching the confirmation screen.  4. The task instances remain as `no_status`, but the black border disappears, so that the task instances are not visibly seen unless hovered over.  **Anything else we need to know**: This appears to happen every time, regardless of operator type. -- This is an automated message from the Apache Git Service.
