May be the problem is on thhis settings:
Payment Methods Requiring Confirmation - I have changed only for payment method that I am using

From the name of the settinh I expect there must be only payment method tha I will to confirm.

thank you Dalibor
You can identify multiple payment methods that require the customer's confirmation prior to submitting the order, as identified in that setting's description:

Identify (using a comma-separated list) the payment modules on your store that require confirmation.

Please note that some payment methods, e.g. the default eway_rapid,stripepay,gps, require confirmation due to the way that they handle the payments but you can identify any payment method (like moneyorder) as requiring customer-confirmation prior to placing the order. That adds another step to your site's checkout process.
