vCenter not showing VMDK in Used Storage

I created a new 4 TB VMFS-5 datastore, and migrated a 1.75 TB VMDK to it. I then expanded the VMDK to 2TB (or 2,047.99999905 GB depending on which pull-down you use). However vCetner shows the size as Zero in the Datastore Browser, and does not show the volume as being used in the Used Storage box in the Client. Inside the VM eveything is normal; Windows Explorer show a 1.99 TB volume. I've attached screenshots as well. The issue is now Veeam doesn't recognize the disk so we can't back up. Has anyone seen this before?

Thanks,

John
