how to stop local credit card form

[Karzoun]

hey there, I was working on this payment gateway for short time, https://github.com/ugurterzi/iyzipay/

it was working fine and it's process was to open a popup window in checkout page to let customer pay, last few days the popup disappeared and my whmcs is showing credit card input.

 

my gateway doesn't support local storage of credit cards and has to make the payment through a link or the popup.

function iyzipay_MetaData()
{
    return array(
        'DisplayName' => 'Iyzipay Merchant Gateway Module',
        'APIVersion' => '1.1', // Use API Version 1.1
        'DisableLocalCreditCardInput' => true,
        'TokenisedStorage' => false,
    );
}

the meta data of the addon is like this,  "DisableLocalCreditCardInput" is disabled but still credit card form shows on checkout page
