I was able to reproduce by performing an upgrade in the admin interface (not able to replicate in client interface). To resolve change app/controllers/admin_clients.php around line 5656 from:
$invoice_data = $this->makeInvoice(
$client,
$serviceChange,
$pricing->currency,
true,
$service->id
);
To
$invoice_data = $this->makeInvoice(
$client,
$serviceChange,
$pricing->currency,
true,
null
);
Cheers
