identity safe exclusion list by itself?

Hi I recently had to go into my norton console and retrieve a site I didnt mean to exclude ( from auto sign in p/w)  and I found a few sites I never told it to exclude, sites I do not visit?

How can this occur?  Can norton pw identity safe be compromised should I be concerned as stupidly I do use it for important things. (its set to ask for pw first but still). I thought this file did not reside on my browser?

 

Thanks for info :)
