Every day is event day apparently!

I know there are a lot of threads surrounding this, but this is still a problem.

I've had it on two occasions this year with events in my calendar. Both times Garmin has thought every day is event day after completing the event. Interestingly, after completing the event my watch asks twice to confirm if that activity was the event I had planned.

When it gets stuck on event day, it "mutes" your daily suggestions and suggests rest days ad infinitum. I can fix it by removing the event (not the activity) from the calendar, which is fine, but it also removes the recovery training suggestions. Which, as I've just completed a marathon, I would like to follow!

I've relayed all this to Garmin support, who haven't replied. Parhaps it will get more visibility here.
