Question [Q] Block sms logging

Hello. On my GTI9001 I have CM11 with Android KitKat. There is an option in SMS settings - Block sms from unknown phone numbers (which is not in my phone address book).
I have set this option and sent test sms from another number. Yes. This sms was blocked. I've got message in my status bar.
BUT. There is no info - what number was blocked, what text of sms was there.
Is there a way to show full info about blocked sms?

P.S. Trying to check it out, I could not get second notification about other blocked sms. Is there a bug or something else?
