Synced calendar event not deletable from iPhone.

I know I'm not the first--but haven't found a solution yet...

I have a phantom, repeating, event I cannot delete from my iPhone

Had a weekly company meeting on my MacBook calendar repeating every Monday at noon.

The company changed the meeting to Tuesday, so I dragged it, in iPhone Calendar, from Monday to Tuesday (at least I think I did that, I don't remember now). That event was on my account of the company's "Google" calendar, not iCloud.

My iPhone (and MacBook Pro) calendars got a new Tuesday mtg. Good

My MacBook Pro calendar mtg on Monday was disappeared. Still good.

BUT, my iPhone, and only my iPhone calendar, still pings me for the Monday mtg. Goodness abated.

AND, I don't see it on my company Google calendar (the one referenced in the image below).

Been trying to delete it off and on for two years. Tried every solution I could find Google searching.

Maybe it still is in my Google Calendar, and is just not displaying.

My guess is that a pointer got confused when I moved the Calendar event, rather than deleting it and recreating a new one.

Or maybe it is how I have set up syncing?

I'm on a very limited data plan, so I set it up to fetch only, I think I did.

thanks for your help.
