In the settings under /e/ OS you can empty the cache for each app individually. This also applies to the Bliss Launcher. This can sometimes help to eliminate malfunctions or false indications.
Here’s how it works to reset the Bliss Launcher: Go to …
Settings > Apps > Bliss Launcher > Storage > Clear storage | Clear cache
“Clear storage” also removes unwanted “placeholders” if the shortcut is left as a space after uninstalling.
