Norton Identity Safe close when i close Edge

Norton Password Manager

Hi.

Norton Identity Safe close each time i close Edge. When i run Edge , NIS close , and it need to open it again.

I guess it happens cause Norton Identity Safe opens on Edge via internet not via Norton Security on my pc as like Google Chrome or IE 11 that the problem doesn't exist. Also i guess it happens cause many users use only Identity Safe without some Norton Antivirus. 

Thanks.
