just some follow up
I had not realized that when it refreshes the fields where I had entered routing and account number it's actually expecting me to enter them again in the form of a confirmation.
I've grown so accustomed to seeing confirmation fields presented on the same form as those fields you're actually confirming and not refreshed and then again on a separate screen.
Even though there's text on this screen to say "confirm" it's in small font and I simply hadn't seen it because my eyes are so drawn to the refresh of the routing number and account fields and not the text above them.
