Why I see information about the authentication angular-oauth2-oidc in the Browser URL

I am using angular-oauth2-oidc for authentication in my angular project.

When I login in the oauth2 server I am redirect to my web page, but I see the information of the authentication in the browser url, then when I navigate to others page, everything works well the information dissapear.

type of information that I have in browser url.

http://localhost:4200/Test/Farmer?code=168C9AF....&scope=openid%20profile%20email%20roles&state=......

I don´t want to see that, I want to see

http://localhost:4200/Test/Farmer

my config is like that

export const authCodeFlowConfig: AuthConfig = {
  issuer: environment.authority,
  redirectUri: window.location.origin + "/home",

My app-routing.module.ts

I don´t have the path home I redirect to Test

const routes: Routes = [
  {
    path:'Test',
    children: [
      {
        path: '', redirectTo: "Farmer", pathMatch: "full"
      },
      {
        path: 'Farmer',
        loadChildren: () => import('src/app/main/pages/...').then(m => m...Module),
      },
      ...
      { path: '**', redirectTo: 'Test'},
      { path: '', redirectTo: 'Test', pathMatch: 'full'  }
}

Best regards
