Actually, now. "Available for all users" is unchecked and greyed out. I also do not see these connections using cnetworkmanager. They appear to be created by nm-connection-editor itself for *some* APs in ./src/applet-device-wifi.c:wireless_new_auto_connection() I do not understand how APs are selected - n-c-e always shows exactly two of them. One is my home AP; another has literal name 'Wireless', but I do not see it in scan result.
