Stealth but no stealth?

Hi folks..

I enabled Stealth mode on my Mac Book Pro (2010 model) but when I look at the system details is says: "Stealth-mode: No"

What could I be doing wrong?

 

Thanks GG...

I tried the Shields up and it showed everything stealthed apart from FTP port 21.

Could anyone tell me how I can stealth this port too please?

 

I found that the FTP port was assigned to AIM (chat app). I disabled that completely and ran the GRC test again. This time I am stealthed on port 21 but still failed on something that was fine before:

How can turning off FTP suddenly make me Pingable?

Down the rabbit hole I go..
