Notifications disappear once I leave a separate app

I set up in my Hub that my text, WhatsApp & BBM are to show up in separate accounts. So since the latest OS update... I've been noticing that I will receive messages at the same time but when I open the hub to view let's say a Facebook message & then close it, the notifications for my text & BBM disappear. So sometimes I don't realize that I have a message until I go into the app to send a message. Anyone know how to resolve this issue so notifications don't disappear until the app is opened?

opening anything in the hub stops all the notification. I don't think there is a way to change this.

Thanx....if this is the case then this 'bug' has to fixed with the next update.
