Pods not deleted after its Rancher App is deleted

Github Issue

Currently, I have a Rancher deployment with 2 clusters. 1 being a generic RKE cluster and the other one being a k3s one.

When deleting a Rancher App on the first one, all goes fine with deploying and deleting Rancher Apps.

However, when deploying a Rancher App and deleting it afterwards on the k3s cluster, the App’s pods don’t get deleted and still run under the radar, not detected by Rancher. Even worse, they obviously still suck up all the resources that I attempted to gain when deleting the App. So of course the cluster fills up over time and cannot accept new deployments, because all other ones are still running behind the scenes.
