Windows 10: Weird message about 2021 reminder - not visible, can't edit

Hi, I tried to set a reminder via Cortana for April 2021. Fine, spoke to Cortana, reminder accepted.

But when I clicked 'Edit this reminder' - nothing.

This is what I see in Calendar: (the event isn't shown as those in 2020 are)




We aren't able to show you some of the events in this time range. But they're still there - they're available via your account provider.

Now just who is my account provider?

If you've seen anything like this.. please let me know. Thanks.
18362.720 (yes, old- staying on this older build for now for 3rd party compatibility reasons).

This is far from unknown, apparently - e.g. searching for that message which I've provided as text -> e.g.

Can't see Win 10 Calendar events 6 months hence. (Although they ARE there.) | Windows 10 Forums

Is this fixed in 2004?

This seems to be a hint:

I use a non-MS email address as my live id login.

Windows 10 Pro and Ergnomic Break Reminder

Hi,



Apologies for the late reply.



Do you remember installing any break reminder software?



It looks like it is a pop up from a break reminder software.



I suggest you to look for this in Programs in features and uninstall it if do not use it.



Try the following steps:

• 
  Press Windows + R keys to open Run Command
  
• 
  Type Appwiz.cpl and hit enter
  
• 
  Search for the programs and un-install it.
  

Regards,
