Calendar automatically setting alert when event created

This year, my apple calendar is automatically adding an alert when I create an event. I swear it used to default as ‘none’ and you had to add the alert. I’ve tried unsyncing the calendar with iCloud and that worked for a minute but then it started happening again. Any suggestions?

iPhone 13, iOS 18

It looks like my calendar was linked to my Gmail account which somehow creates the automatic alerts. If you go into settings > apps > calendar and change ‘default calendar’ to be one of your phone calendars, the alerts seem to stop
