Wrong redirection after payment (monetico)

Hello,

I'm implementing this module for a website using monetico with drupal commerce 2.x.

I could successfuly setup a test environment and I can access to the bank page in order to make a test payment.

But, after payment, I'm redirected to the : /checkout/X/payment (where X is my order number).

And, as the role of this page is to redirect the customer to the payment page, it create an infinite loop :

Go to the bank website > Pay > redirected to the site, that redirect to the bank website > Pay > Etc...

I already implemented other payment methods and, generally, there is a setting for the merchant return URL, but I didn't see this configuration neither on the monetico website, neither on the module configuration.

Could you point me the right direction in order to fix that problem ?

Thank you

Alex
