tsconfig removes the paths setting

I use react through CRA with typescript. Here is my config from tsconfig.json

 {"compilerOptions": {"target": "es5","lib": ["dom","dom.iterable","esnext"        ],"baseUrl": ".","paths": {"my-lib": ["./node-modules/my-lib/src"            ],"my-lib/*": ["./node_modules/my-lib/src/*"            ]        },"allowJs": true,"skipLibCheck": true,"esModuleInterop": true,"allowSyntheticDefaultImports": true,"strict": true,"forceConsistentCasingInFileNames": true,"module": "esnext","moduleResolution": "node","resolveJsonModule": true,"isolatedModules": true,"noEmit": true,"jsx": "react"      },"include": ["src"      ]    }

However, after running the npm start script, the" paths "setting automatically disappears from the config.

Please help me solve this problem. Thanks.
