"editor.rulers" not working

I would like to add some rulers
My Config
` "editor.rulers": [
{
"column": 72,
"color": "#9a32ad"
},
{
"column": 89,
"color": "#000000"
},
]`
This does nothing, I also tried passing an empty array but that also did nothing (The default ruler was still there, although I don't know why I have a default ruler as the default settings json file has a empty array for editor.rulers)

Additional :
OS : Zorin 16.2 (Based on Ubuntu 20.04)
Do tell If I can provide any other info
