Calendar issue with birthdays (Outlook)

Hello everyone,

I just got my Forerunner 165 Music and I'm having a bit of trouble with the calendar Glance.

It shows every birthday of my Outlook calendar.

I removed every single one of them in Outlook, synced the watch, disconnected everything, re-paired, rebooted several times, what-have-you, but it all still appears.

My Google and Outlook contacts don't mention the birth dates anymore and the calendars are clean, yet, they're still on the watch.

This makes the glance completely unusable and I have no idea what to try next.

Help, anyone?
