Glance: primary event disappears

I have a primary event scheduled for April 11.  I used Garmin Run Coach to make a plan.  Most days I used the FR265 glances to go to the primary event, then the DSW, then the run.

In the last two weeks, many times I look at my watch and it reports "No Primary" event.  I log into the app, open the event in Garmin Connect App Calendar, and click "Send to device" it says "You'll see it the next time you sync."   I sync the watch and it does appear, and I can do the DSW.

The next day, or the next couple of days later, it happens again, the watch says "No Primary Event"

I'm on normal release firmware, and I only have on event on my calendar.  Anyone else seeing this?
