Socks5ProxyAllTraffic not working

[theonewhopassed]

hello
there is a option in the official website about socks5 proxy being able to handle all the traffic through itself but the option doesn't work in the wiresockui

when i try to add the line 'Socks5ProxyAllTraffic = true' it doesn't let me save

ignore the other parameters in the picture that are red too I've been testing with the correct parameters
