Hi, this is a bit hard to explain but on my Galaxy S6 Verizon with latest software I am totally confused by the calendars apps and icons. I use Google calendar exclusively but whenever I go to schedule an appointment the phone asks me which calendar I want to schedule the appointment with. It show two icons that are exactly the same, except one is blue and one is green. On my front page, the icon is green and when I go into the apps section to delete the blue icon(app?) there is no blue calendar icon, just two green calendar icons??!! I can't for the life of me figure out what these icons are and why there are two and which is Google and which is not. Help please if you can.
