It sounds like you're sharing the calendar with some other system that is overruling what you do on your iPhone to avoid the alerts.
Investigate the other places your calendar may be set and have your iPhone's actions overruled.

I checked on my google calendars account on a separate computer and it was set to automatically alert 30 minutes before. Have removed that in settings and re-synced. Problem solved!

Delighted to hear it! Enjoy your iPhone.

I have a similar problem, tried this solution but it didn't work for me....

You may be on to something - all my recurring events get reset back to alerting me 15 mins before even if I set the Alert to None in the phone.
Does that mean I have to check the Mac Calendar setting, the iCloud setting, and the iPad Calendar settings?
