Desktop clock disappeared...

[6rtury]

Updated Anuko World Clock yesterday to v.6.1.0.5418 and the one clock that has appeared on the bottom right of my desktop since I set up this computer in 2019 has disappeared. I've gone through all the options and they are fine. I tried changing one option and then changing it back to my setting hoping I could jiggle it to appear. No such luck. Any suggestions? My preferred location is the bottom right of the desktop.
Thanks for any suggestions.

Try adding a new clock on desktop. Does it work?

Yes, it does.

Have to add that I haven't rebooted since I updated (because I need to keep some real-time data feeds running), although not sure why that would make a difference. Will reboot soon and then see.
