Identity Safe login for Costco

I am a new forum user.  I have NIS 2012 installed on 3 Windows 7 systems.  I have recently set up Identity Safe on two of them. Most of it is working well.    I have a few problems and will take them one post at a time.  The first one being the login for Costco.  Since on the login page it offers a new registration opposite your login, ID Safe puts the password in the login AND the password location in the new registration box.  This causes it to tell me that I have entered wrong info.  If I remove the password from the New Registration box, it will then work. I have tried auto save and manual setup on the site.  It happens on both of them.   Is there something I am doing wrong to cause this to happen or is it a problem with the Costco login site?
