Autofill of usernames and passwords sometimes/not

hello I have Norton internet security version 18.5.0.125

 

frustratingly my user names and passwords aren't auto filling out

 

sometimes they do, sometimes they don't

 

 

if they don't I click on identity save and available log ins for this page is usually not there on these instances, so I click on manage logins and low and behold in the background all of a sudden it has now auto filled the username and password although this does not always happen

 

it has like I said been frustrating, but, when I spoke to my dad he said his was doing the same, when I use my husbands PC his is doing the same too!

 

it has just been happening the last few weeks but after the conversation with my dad I thought I would investigate.

 

I use a notebook so downloaded my software from Norton and use the key I physically own to activate it, my husbands was installed using a cd and same activation code as mine as we purchased 3 licenses

 

any ideas my peeps?

 

thank you so much in advance :D
