Build error while compiling for production with Angular CLI and 1.0.0-rc.4

Hi,

I'm getting build errors when building for production the app using angular cli with: ng build --prod
It compiles fine if I compile with JIT.

ERROR in : Unexpected value 'CovalentLoadingModule in /node_modules/@covalent/core/loading/loading.module.d.ts' imported by the module 'CoreModule in /src/app/core/core.module.ts'. Please add a @NgModule annotation.

The above error shows the error with CovalentLoadingModule but the bellow code shows with the CovalentLayoutModule. It shows the error with the first package declared in imports in NgModule...
I tried falling back to importing all packages in '@covalent/core' path but it didn't work either.

import { CovalentLayoutModule } from '@covalent/core/layout';
import { CovalentStepsModule  } from '@covalent/core/steps';
import { CovalentLoadingModule } from '@covalent/core/loading';

@NgModule({
  imports: [
    CovalentLayoutModule,
    CovalentStepsModule,
    CovalentLoadingModule,
...
  ],
  declarations: [
...
  ],
  exports: [
...
  ],
  providers: [
...
  ]
})
export class CoreModule { }

Angular Version: 5.2.3
Angular CLI Version: 1.6.7
Angular Material Version: 5.1.1
Covalent Version: 1.0.0-rc.4

Ok, I closed the issue, seems to be resolved when using TS 2.6.2
