In a lot of use cases CommTrack mobile worker needs to be associated with potentially multiple locations (i.e. 50-100 facilities per mobile worker). This page would walk you through the bulk upload tool to create multiple locations, and the tool to associate each CommTrack mobile worker with multiple locations.

Once you are done with these two sheets, upload it and click 'Create Mobile Workers'. After you see the line "Your bulk user upload is completed!", go back to Mobile Worker page and check if they are associated with facilities you assigned them.
Displaying all the facilities that that person is linked to is a future feature, but is not currently implemented. Right now we just show 1 facility that the mobile worker is associated with. In matt's case, Go to CommTrack and you would see the Supply Point he is associated with clinic 6.
