Can't add VM to Unraid

When we're trying to add a virtual machine to Unraid we can click an icon for the preferred os but when clicked there's a blank page and the page never loads. This effectively means we cannot add a virtual machine to our server. See attached the screen we get, the settings for VM manager and diagnostics, has anybody else had this problem too and is there a fix?
