Why react project running first time to show project folder name path? Don’t show Home path first run the project

When I run the react project by npm start in the project then the auto path is created project folder name.
For example http://localhost:3002/bug-palace

But after the run, it was supposed to do http://localhost:3002 shows.
When I clicked Home than show me the right home path http://localhost:3002

please solve the problem, anyone.
