Decryption not working

I'm using Wireshark on OSX and it's seems to be working ok, I'm seeing the icon for monitor mode and it's capturing the packages. However, when I add the WPA-PSK key for decryption, it only seems to decrypt LLC, NetBIOS, STP, SNA, RPL, X.25 and Vines LLC protocol. I still don't see UDP or TCP for instance, and a lot of 802.11

I tried the different settings (Assume packets have FCS, Ignore protection bit) but that didn't help. I used this tool to generate the PSK; http://www.wireshark.org/tools/wpa-psk.html

Is there another setting that I'm overlooking? How can I make sure all packages are decrypted?
