Strange circular USB icon in Finder

findericonusb

I've got a minor problem which has been irritating me for some time. Whenever my Mac has a USB storage device mounted in Finder, it shows a circle instead of the usual USB icon.

I'm not sure when this started (Mac is running 10.14.4 at the moment), but it is consistent with all storage devices and it's strange because the icon appears normally both at the top of Finder and on the Desktop.

Please see the images below for clarity:

Does anyone have any idea why it is the case that this strange circle appears as the icon in the side bar for all USB storage devices?

If so, is there a way I can restore the standard USB icon you would expect (and can see at the top of the Finder window)?

These icons are a bug caused by the app What's Your Sign?. Uninstall the app, reboot, and your Finder sidebar volume icons should return to normal. There's an open issue for this bug at the What's Your Sign? github so it doesn't appear as if the issue is fixed even in the most recent release.
