Everything was fine till yesterday, today all of a sudden I noticed my custom windows terminal theme showed just two colors the primary background color and font color as white for every word. Then I hover over my settings.json file I saw warning popping up in
$schemas: "https://aka.ms/terminal-profiles-schema" with warning "Draft 2019-09 schemas are not yet fully supported terminal"

Everything is working fine except some words are not highlighted in a different color, which earlier was working fine.
