N360 22.5.0.124 not infilling some passwords

Greetings. I have a further problem with N360 22.5.0.124 not infilling some passwords including for account.norton.com. I believe the problem started when I deleted some logins from Identity Safe (including some Norton Logins with long defunct passwords). Can someone please help, as my memory for passwords is appalling. ALSO EVERY TIME I ATTEMPT TO LOG INTO MY NORTON ACCOUNT, AS WELL AS REQUIRING THE PASSWORD, IT ALSO WANTS ME TO COPY 2 RIDICULOUS  BARELY READABLE WORDS INTO A TEXT BOX.  I am getting very frustrated. The main reason I stick with Norton is for its Identity Safe feature, which hitherto has always worked well. I use IE 11, Windows 7 SP1. Thank You
