Great Antivirus, but still remains one bug.

I just updated my Bitdefender, and yet everytime I view it on the app store, it tells me to update. I went to the updates section on the mac app store nothing but an update towards a game I play. So is this a bug regarding the software or is it the Mac App store bug? Aside from that, theres no problem with anything else.
