ngx-select-ex: Can't bind to 'formControl' since it isn't a known property of 'ngx-select'.

Hi, When I used the single select, I got this error.

HTML

• It’s the same contained in the doc.

TypeScript:

• I modified it slightly since I passed it a list containing objects with these fields: id, ds and selected.
• The local variable ‘_ngxDefault’ stores ‘this.lista[idx].ds’ (‘lista’ is my collection of items).

My feature module:

• import {INgxSelectOptions, NgxSelectModule} from ‘ngx-select-ex’;
• const CustomSelectOptions: INgxSelectOptions = { // Check the interface fo more options optionValueField: 'id', optionTextField: 'ds' };
• NgxSelectModule.forRoot(CustomSelectOptions)

Best regards.
