Multiple Logins Driving me Crazy

I recently upgraded to Norton Internet Security 2012 (build 19.2.0.10) on my windows XP machines with IE8.  The program now offers me multiple logins for almost every page I visit, some correct and some not correct.  It's causing some sites to lock me out bacause I don't know which one to pick!!  Seems you have to go into edit mode and pick through each of them to find the right one.  Luckily I keep passwords in a spreadsheet, but it's very time consuming to sort through.  Before the upgrade the program seemed to know exactly which login I needed for each and every page, with no confusion.  This new version seems to have dredged up a bunch of old logins or something (often 5 or more per site).  Help!
