Clock icon next to some apps on macOS Mojave Notice the clock or piece-of-pie icons next to 3 of the apps in this screenshot of the Finder. The icon has been there for two days. All three apps work; I have used each of them.



➥ What does that icon mean? 

➥ Is it a problem? What can I do to fix it?

Using macOS Mojave 10.14.5 on a Mac mini (2018).
Bug

Apparently, the icons where caused by an innocuous bug. 

After restarting the Mac mini, the icons were gone.
