Ionic V4: Problem in routing

Ionic Framework ionic-v3
1

Hello all,
I am facing an error while routing inside my app.
The problem is this.
I have a tabs page and my app.routing code this:

const routes: Routes = [
  { path: '', loadChildren: './tabs/tabs.module#TabsPageModule' },
  { path: 'account', loadChildren: './account/account.module#AccountPageModule' },
];
@NgModule({
  imports: [
    RouterModule.forRoot(routes, { preloadingStrategy: PreloadAllModules })
  ],
  exports: [RouterModule]
})

But when the app is initialized another page “signin.page” which is not declared in the routes is loading as home page. The signin.page is a modal page by the way.

Struck with this from yesterday

Please help!! Thaks in advance.
