Rancher-2.9.0 project/namespace setting always be restored the next day

I installed Rancher 2.9.0 on EKS using Helm, and now I have a problem. When I create a project A under projects/namespaces and move the namespaces of services b, c, d, e… within the cluster to project A, the next day they revert back to their original state, and services b, c, d, e… are back outside the project.

Thanks for help
