TypeScript Interface Checking issue

Just a report of a wrong error detection:

I am on Resharper 2017.2 EAP 12 and have the following issue in my Angular 1.6 app: (TypeScript 2.1, VS2015)

My Code: 

export class ActionController implements ng.IController { // ReSharper shows Error on ng.IController: Controller declares Interface but does not implement it

    $onChanges(onChangesObj: angular.IOnChangesObject): void {...} // ERROR

}

However when I use 'Add missing overload signature' fix on the error, two implementations get inserted:

$onChanges(onChangesObj: angular.IOnChangesObject): void; // The same as I used!
$onChanges(onChangesObj: any): void;

As a workaround I changed my signature to the second interface definition and the error went away.

Another issue: I removed my $onChanges method and used the 'Generate \ overriding members' -> $onChanges action. 

Then Reshaper throws an Exception: "An item with the same key has already been added". I have submitted this exception.
