ADDITIONAL INFORMATION
I see code at https://invent.kde.org/network/kdeconnect-kde/-/blob/master/plugins/notifications/notification.cpp#L101 which looks like it should only be adding the colon if m_text.IsEmpty() is false. I haven't debugged this but I wonder if maybe m_text contains just blank spaces, so isn't really empty, and if so, whether you can check for that. Thanks!
