MenuBar & Add/Remove & Redraw

Hello,

We have changed from 9.81 to 10.3.0.
Now we have a redraw problem after remove/add a control to menubar.

    CXTPCommandBar* pMenuBar = pCommandBars->GetMenuBar();
    CXTPControls* pMenuControls = pMenuBar->GetControls();

if (a)
  pMenuControls->Remove(s_pOldMenu);
else
  s_pOldMenu = pMenuControls->Add(xtpControlPopup, nID, "", 2);

Bug or feature ?
Best solution ?

With this , it will work
    if (pMenuBar)
        pMenuBar->Redraw();
