iOS Reminders from Obsidian Full Calendar (need help refining it)

Hi everyone.

I created this shortcut which scans Full Calendar events in the designated folder (Calendar in my case) a while back, and it seemed to work well at the time.
The problem I’m having at the moment, is that it isn’t identifying duplicate reminders anymore.
It’s still taking the calendar events and adding the reminders, but it’s duplicating entries each time it’s run.

Can somebody please help me fine tune this?

Many thanks in advance.
