TWebSideMenu causing Compiler Error

When placing this component on a simple form, I get this compiler error:

[Error] uMain.pas(140): Incompatible types: got "TInputType" expected "TSideMenuItemType"

My pas file:
unit uMain;

interface

uses
System.SysUtils, System.Classes, JS, Web, WEBLib.Graphics, WEBLib.Controls,
WEBLib.Forms, WEBLib.Dialogs, Data.DB, XData.Web.JsonDataset,
XData.Web.Dataset, WEBLib.SideMenu, WEBLib.ExtCtrls, WEBLib.ComCtrls,
Vcl.Controls, WEBLib.Login;

type
TFormMain = class(TWebForm)
WebPanel1: TWebPanel;
WebPanel2: TWebPanel;
PageControl_Main: TWebPageControl;
PageCtrl1_Sheet1: TWebTabSheet;
WebPageControl1Sheet2: TWebTabSheet;
WebPageControl1Sheet3: TWebTabSheet;
WebTabSheet1: TWebTabSheet;
WebLoginPanel1: TWebLoginPanel;
WebSideMenu1: TWebSideMenu;
procedure WebFormCreate(Sender: TObject);

private
{ Private declarations }
public
{ Public declarations }
end;

var
FormMain: TFormMain;

implementation

{$R *.dfm}

procedure TFormMain.WebFormCreate(Sender: TObject);
begin
PageControl_Main.ActivePage := PageCtrl1_Sheet1;
end;

end.

The projekt can easely compile without the TWebSideMenu. Anything i'm missing in configuring the component?

If you remove the three default menu items it works again.

Is this TMS WEB Core v2.7.0.1, as I could not reproduce this here so far.

Yes my version of TMS Web Core are v. 2.7.0.1

I cannot reproduce this. Is your TMS WEB Core library path setup correct, i.e. it points only to the latest version "Core Source" subfolder? (See Help, Options, TMS WEB, Library path)
