NS 2015 shows too few remaining day subscription?

Today 06/15/2015, I just got NS 2015 for 5PCs on a 2 years subscription.  However, NS shows a subscription status saying, "196 Days Remaining".  This can't be possible for it should say, "730 Days Remaining", which is 2x365 days.   So what's up with NS?  Does it has a bug or is it this version so buggy that it can keep the subscription days correctly?  I hope Symantec has a GOOD answer for this.
