Topics get deleted automatically

I have installed a confluent operator using Helm charts and as a cluster-wide operator (namespaced: false).
But every time I tried to add topics via the CRD with a different namespace, the topic get deleted automatically as soon as reconciled.
But if I create the topic with the same namespace as the cluster then it’s fine.
Is any configuration I need to put to avoid such deletion?
