This is a known issue and documented in CSI driver KC section https://www.ibm.com/docs/en/spectrum-scale-csi?topic=231-limitations as
'In dynamic provisioning, if the PVC is deleted before it goes into bound state then the fileset that is created for that PVC might not get deleted. You need to delete the fileset manually."
