Airodump-ng finds way more AP's than network manager. Help!

When I run airodump-ng, it's able to pick up 20+ AP's and a few of them didn't have any encryption. However, I tried to connect to one of those networks (first brought card out of monitor mode and such) by clicking the regular network connections icon in the top right, but it only lists 2 or 3 networks and weren't the open ones I found when scanning using airodump-ng. Am I missing something here? Oh yeah almost forgot to mention that I'm running kali on a raspberry pi 3 b+ and I'm connected to it through HDMI with my external wireless adapter.

Hopefully someone can point me in the right direction and I can gladly provide more details if needed.
