 # Error Rolling Back Service Chart With etcd
 
-If rolling back a service with Bitnami etcd, the `helm rollback` could fail when going from an etcd chart version 9.x to an etcd chart version 8.x.
+If rolling back a service with Bitnami etcd, the `helm rollback` could fail when going from an etcd chart 9.x version to an etcd chart 8.x version.
 This is because the Bitnami 9.x etcd cluster StatefulSet and Pods have the `app.kubernetes.io/component=etcd` label and the
 Bitnami 8.x etcd cluster StatefulSet and Pods do not, causing the StatefulSet to complain on rollback.
