Stop calendar from asking me if I want to turn on notifications
I found the answer and am posting it here for anyone that's having the same issue. Open the calendar app, go to three dots at the top, select settings, go to set default reminders, set both to none. That should stop the anniying pop up.  I am still looking for a way to rearrange color order.  Apparently they will let you do it with stickers but not with colors.
