When I set up an event in iphone 6 calendar I set the first alert for "one day before," then the second alert for "2 hours before." As soon as I click "done," the alerts switch places. If I don't fix them, i don't get both alerts, so I click edit, fix them, then click "done." As soon as I click done again, they switch again! I have to do this several times before it will stay correct when I click done. I have even tried setting the secondary alert first. Even after all this, sometimes later when I go back into an event, the alerts are switched again. I thought maybe w/one of the recent Apple updates they would fix this, but no. Another recession product!
