AUTO-FILL-IN FROM TOOL BAR NOT WORKING RIGHT

I have NIS 2009 Version 16.7.2.11 Why would auto-fill-in from the tool bar just stop filling in names and passwords, it's building  new auto-fill-in's and not using the ones in manage log-ins, there's about 10 from Norton that have no password or name and the rest of them are there but are just not being used, sometimes I have to look them up manually to do a fill in, Thanks, Gorpy1
