Issue/Introduction

• Unable to remove vApps in VMware Cloud Director(VCD), VM(s) are in an UNKNOWN state.
• VMs already deleted in vCenter Server, cannot remove from VCD.
• An import of a VM from vCenter failed, now the VMs cannot be removed from VCD.
• As the VM is displaying an 'UNKNOWN' status in the VCD UI, all of its power and management options are currently greyed out
• You can have VMware Cloud Director Availability(VCDA) replication created to migrate VMs but when the replications were deleted, it would not delete the replication from destination site. 
• Issue with deleting VAPP and VMs and you will get the below error message:

 - The operation could not be performed because the object is in an invalid state.
