How do I remove an empty, Deleted Vault Store which still shows up in DA "Searchable Vault Stores"

I had created a test vault store, did not add any content to it, and deleted it within the VAC.  The deletion occurred properly, but now when I check DA the Vault Store is listed under "Searchable Vault Stores".  How do I go about deleting the remnants of this test vault store so that they no longer appear in the Searchable Vault Stores when creating Cases in Discovery Accelerator?

Thanks in advance.
