The Sign In Screen appears and I briefly see the Username or Customer # field populate than the field contents disappear. Then the Password field populates but I don't know what's in it because it's hidden.
I also tried in a New Private Window with the same result. When I right click on the first field and choose 1P from from the dialog window the same thing happens.
