I am trying to configure authorize.net payment settings in an magento 2 install. When I edit the payment method values, the default values are reset after I save (i.e. I enable Authorize.net, save and it is disabled).
I tested other payment methods such as braintree and paypal and they all worked fine as expected.
See example screenshots.
Before save - with updated settings input:
After save - returned to default or blank.
I have not been able to find anything online describing this behavior. Any thoughts?
