When some of the resources needed to create a subscription for operator hub already exists in the namespace, it's not recreated or removed creating a subscription.

In my example, I had a failed "csv" resource in the namespace, that blocked creating a jaeger-operator pod:

oc get csv         
NAME                      DISPLAY                    VERSION   REPLACES   PHASE
jaeger-operator.v1.17.6   Red Hat OpenShift Jaeger   1.17.6               Failed

I would assume that this failed csv will be deleted and replaced by a new one, that will eventually reach success state and will create a new jaeger-operator pod
