Just downloaded Norton Standard security (for 1 year) and my pc's notification tab is telling me it will expire in one day

Hi ,

I just downloaded (19/02/2018) the Norton Standard security today and my notification pop-up in the task bar is telling me "Norton Security, expires in 1 day. Renew your subscription." Why is this coming up if I only downloaded it today, it is supposed to expire in a years time. I'm confused why is it saying this? Please help.

Many thanks,
