Notifications badge icons not working

[Curlysusie]

Have checked all settings regarding notifications that I can find and every notification is on. But Facebook snapchat, viber, WhatsApp,line or Twitter don't show any badges at all. Only message and email do.  Is there a setting I'm missing?there's also no peek option available
