Title config in package.json is not working anymore, but still remaining in README.md

I've trying to customize my project's commit types, but found that title doesn't make any effect. And i notice, in source code, it seems engine.js won't use title, is there something wrong?

README.md:

cz-conventional-changelog/README.md

Line 37 in a93bd96

"title": "Features"

engine.js:

cz-conventional-changelog/engine.js

Line 45 in a93bd96

name: (key + ':').padEnd(length) + ' ' + type.description,
