I've noticed this issue over several iOS versions but it isn't a big deal, more cosmetic than anything, so never posted or told Apple about this following iOS calendar bug.
1. Set an event and then a first alert for say... 1 hour.
2. Then set second alert for 15 minutes.
3. Save it.
Now view the iOS Event you created summary screen and you'll see:
Alert 15 minutes before
Second Alert 1 hour before
Obviously backwards and impossible. Luckily the alerts sound in proper order, hence a cosmetic rather than functional bug.
If you have your iOS devices sync to your computer, or create a new Event on iCal OSX, the OSX iCal display is correct event for a sync'd event from an iOS device where the Alerts display in backwards order, as per above:
Alert Message 1 hour before
Alert message 15 minutes before
I spoke with AppleCare yesterday, and the rep was surprised to have never seen this (tried on her iPhone) or never heard about it in all these years. I think I noticed this back to iOS 5. Odd it's never been fixed, albeit minor.
