Problem with inheritance through mapped classes (in previous versions worked correctly)

IDE: Visual Studio 2013
Version: 8.4.96.2033
Description:
In previous versions the following code worked properly:

Class1.pas

namespace SharedProject1;

interface

type
  TC1 = public class(Object) mapped to 
    {$IF ECHOES}  
    TNetC1
    {$ELSEIF COOPER}  
    TJavaC1
    {$ELSEIF TOFFEE}
    TCocoaC1
    {$ENDIF}
  public
    constructor; mapped to constructor; 
    method Add(AValue: Integer): Integer; mapped to Add(AValue); 

    property pro1: Integer read mapped.pro1;
  end;

  {$IF ECHOES}
  TNetC1 = public class
  private
    Fpro1: Integer;
  public
    constructor; 
    method Add(AValue: Integer): Integer;
 
    property pro1: Integer read Fpro1 write Fpro1;
  end;
  {$ELSEIF COOPER}
  TJavaC1 = public class
  private
    Fpro1: Integer;
  public
    constructor; 
    method Add(AValue: Integer): Integer;

    property pro1: Integer read Fpro1 write Fpro1;
  end;
  {$ELSEIF TOFFEE}
  TCocoaC1 = public class
  private
    Fpro1: Integer;
  public
    constructor; 
    method Add(AValue: Integer): Integer;

    property pro1: Integer read Fpro1 write Fpro1;
  end;
  {$ENDIF}

implementation

{$IF ECHOES}
constructor TNetC1;
begin
  Fpro1 := 1;
end;

method TNetC1.Add(AValue: Integer): Integer;
begin
end;
{$ELSEIF COOPER}
constructor TJavaC1;
begin
  Fpro1 := 1;
end;

method TJavaC1.Add(AValue: Integer): Integer;
begin
end;
{$ELSEIF TOFFEE}
constructor TCocoaC1;
begin
  Fpro1 := 1;
end;

method TCocoaC1.Add(AValue: Integer): Integer;
begin
end;
{$ENDIF}

end.

Class2.pas

namespace SharedProject1;

interface

type
  TC2 = public class(TC1) mapped to 
    {$IF ECHOES}  
    TNetC2
    {$ELSEIF COOPER}  
    TJavaC2
    {$ELSEIF TOFFEE}
    TCocoaC2
    {$ENDIF}
  private
  protected
  public
  end;

    {$IF ECHOES}
  TNetC2 = public class(TNetC1)
  private
    Fvar: Integer;
  public
    constructor; 
  end;
  {$ELSEIF COOPER}
  TJavaC2 = public class(TJavaC1)
  private
    Fvar: Integer;
  public
    constructor; 
  end;
  {$ELSEIF TOFFEE}
  TCocoaC2 = public class(TCocoaC1)
  private
    Fvar: Integer;
  public
    constructor; 
  end;
  {$ENDIF}

implementation

{$IF ECHOES}
constructor TNetC2;
begin
  Fvar := 1;
end;
{$ELSEIF COOPER}
constructor TJavaC2;
begin
  Fvar := 1;
end;
{$ELSEIF TOFFEE}
constructor TCocoaC2;
begin
  Fvar := 1;
end;
{$ENDIF}

end.

Now the following code fails in all platforms.
With the methods it works correctly, but not with the properties.

  var aa := new TC2;
  var bb := aa.Add(2); // OK
  var cc := aa.pro1;  // not OK

Error 1 (E406) No overloaded method “pro1” with these parameters on type “TC2”, best matching overload is “class method pro1(&self: TC1): Int32” C:\Mis archivos\Projects\SendaSoft\Oxygene\Bugs\Bugs 2016.08.20 - 1\org.me.androidapplication1\WPFApplication1\Window1.xaml.pas 32 13 WPFApplication1

Error 2 (E406) No overloaded method “pro1” with these parameters on type “TC2”, best matching overload is “class method pro1(&self: TC1): Int32” C:\Mis archivos\Projects\SendaSoft\Oxygene\Bugs\Bugs 2016.08.20 - 1\org.me.androidapplication1\EmptyProject1\Program.pas 21 13 EmptyProject1

Error 3 (E406) No overloaded method “pro1” with these parameters on type “TC2”, best matching overload is “class method getpro1(&self: TC1): Integer” C:\Mis archivos\Projects\SendaSoft\Oxygene\Bugs\Bugs 2016.08.20 - 1\org.me.androidapplication1\org.me.androidapplication1\MainActivity.pas 31 13 org.me.androidapplication1

Is there a workaround for this problem or reinstall the previous version of Elements?

I attached project and screenshot.
