alerts on watch do not match phone

This was already asked once and the answer did not resolve my issue so I wanted to follow up.

I have a series 3 watch and had not updated etiher my watch or phone in over a year. I updated both very recently and now have this misalignment.

my Watch has started to alert every calendar event 1 hour before. Even if though the default reminders on the meeting for my phone (and outlook calendar) are set to 15 minutes before the meeting.

I have reset watch. I have unpaired and repaired the watch and still happens. The watch the calendar is set to mirror phone.

How do I get this to correctly mirror my phone?

The initial support response was as follows and yes they understand correctly. Yes I have run thru the recommendation with no luck of resolution:

Thank you for using Apple Support Communities. From our understanding, you have calendar events on your iPhone set to remind you 15 minutes prior to the schedule event or not at all however, your Apple Watch will remind you an hour before the event regardless of how it is set up on your iPhone, do we have that right? If so, does this happen with every event or a specific event? Does it continue if you delete that event and re-add it? Are there any software updates available for either device?

On your iPhone, if you go to Settings > Calendar > Default Alert Times, is that set to None or something else? Does changing that setting make a difference?
