Started seeing the same bug after upgrading to 18.04 LTS. It only happens when I have some "security" update(s), indicated by red icon color. After the updates are installed, the notification icon color changes to blue (indicating normal non-security updates) but icon stays in the tray, even though there is no further updates available. This notification icon can only be cleared by leaving the KDE session.
