VUV missing from response

[hdeters]

Today we noticed that a currency that used to be returned by a history GET is no longer returned. Vanuatu Vatu (VUV) is no longer in the response body. Just wondering if you could provide some visibility into why this currency is no longer reported as it is still listed under supported currencies.
The endpoint we're hitting is: https://apilayer.net/api/historical?access_key=[secret]&date=2022-07-12
I was not able to create a support ticket on the site so asking here.
