Hello @suhag79,
Try running Check Compliance for the vSAN Default SP that is applied to the Object via Home > Policies & Profiles then:
If this doesn't work you could always create a new SP (same as the Default SP or not), apply this SP to the Performance stats Object then apply the Default SP back:
Alternatively if you are not using Performance stats yet and don't need to retain them you could disable and re-enable the Perfromance service to create a new Stats DB Object but this shouldn't be necessary.
