### Apache Airflow version 2.6.0 ### What happened After upgrading Airflow to 2.6.0 from 2.5.1 We are losing the previous tasks on the Airflow web server GRID . These tasks are executed correctly however they are not displayed.  The behavior is curious, since the previous tasks are finished. An example is that if I mark the last one as Failed. The Grid is updated and shows me the tasks again.  Also if I select this option. You can see that the tasks are found, but they are never shown.  But finally I do not do a clear or anything, mysteriously the tasks in the Grid are loaded correctly (sometimes are loaded with the correct state "sucessfull" other time as in the image without any state)  As you can see in the image, all the task are 'found' but not loaded on the grid. Even all the previous task are finished succesfully. We are also seeing other behavior. Since we 'lose' the previous tasks, the DagRuns never finish and this results in the next DagRuns never being executed. That is, our Dummy task (Start) is not launched because since we do not have the previous tasks, we do not have their states. ### What you think should happen instead All the task should be displayed correctly with their correct state ### How to reproduce We don't know, we have days where all the DagRuns are with their correct tasks and status. Other cases where having the DAG correctly starts to go wrong and we end up losing the tasks. And other cases where nothing is affected. ### Operating System "Debian GNU/Linux 11 (bullseye)" NAME="Debian GNU/Linux" ### Versions of Apache Airflow Providers apache-airflow-providers-amazon==8.0.0 apache-airflow-providers-celery==3.1.0 apache-airflow-providers-cncf-kubernetes==6.1.0 apache-airflow-providers-common-sql==1.4.0 apache-airflow-providers-docker==3.6.0 apache-airflow-providers-elasticsearch==4.4.0 apache-airflow-providers-ftp==3.3.1 apache-airflow-providers-google==10.0.0 apache-airflow-providers-grpc==3.1.0 apache-airflow-providers-hashicorp==3.3.1 apache-airflow-providers-http==4.3.0 apache-airflow-providers-imap==3.1.1 apache-airflow-providers-microsoft-azure==6.0.0 apache-airflow-providers-mysql==5.0.0 apache-airflow-providers-odbc==3.2.1 apache-airflow-providers-postgres==5.4.0 apache-airflow-providers-redis==3.1.0 apache-airflow-providers-sendgrid==3.1.0 apache-airflow-providers-sftp==4.2.4 apache-airflow-providers-slack==7.2.0 apache-airflow-providers-snowflake==4.0.5 apache-airflow-providers-sqlite==3.3.2 apache-airflow-providers-ssh==3.6.0 ### Deployment Official Apache Airflow Helm Chart ### Deployment details _No response_ ### Anything else After upgrading from 2.5.1 to 2.6.0 ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
