rqt_graph does not show all the nodes in ros2 node list?

edit

OS: Ubuntu 18.04

ROS Distro: ROS2 Foxy

When I run ros2 node list I get a large list of nodes and different namespaces. But, when I try to visualize this in rqt_graph it does not show all the same nodes even after switching to Nodes/Topics (all) and reloading multiple times. It will only show one namespace and not even all the nodes from that namespace... I want to visualize to make sure all the topics are connecting together properly.
