@ThatMojo, I also ran into this once while testing.
In core/class/commoninvoice.class.php buildEPCQrCodeString() I changed

                // $totalTTCString = number_format($this->total_ttc, 2, '.', '');
to
                $totalTTCString = number_format($this->getRemainToPay(), 2, '.', '');

I haven't had the time to test it properly, so it could have strange side effects.

Cheers,
Michael
