Date on Notifications screen

[winday]

After swiping down for Notifications, once the little toolbar clears away I'm left with the battery indicator -- and a date. But it's not today's date, and it's not the date of the last time I charged my Versa, nor is it the date of the last notification received or read or sent.

Versa notification screen with date

What is that date, what's triggering it, and how do I get rid of it or make it change?

Hi, restart your Versa several times with the two buttons method and seen ifthat solves the date problem. Usually it does the trick. Regards kuzibri

That worked. But does anyone know what that date signifies? What app puts it there?

Fitbit iOs puts the date there. Regards kuzibri

OK, but what does the date signify? It's not today's date. Yesterday when I rebooted my Versa the date changed to yesterday's date. This morning, it still shows yesterday's date!

So is it the date of last reboot? Why would they bother to put that there?
