Hamburger Menu & Overflow continues to fade

Question

I create an application in codenameone and I have problems with the hamburger menu and the overflow menu, they continue to disappear on some pages, sometimes they are, and sometimes they go away

See the attached image, these two menus keep going and sometimes come to the application

Is there a way out?

I am using the toolbar API to add commands

tb = new Toolbar(); 
tb.getStyle().setBgImage(new RR().getR().getImage("newmenuimage.png"));
tb.setLayout(new BorderLayout());
f.setToolbar(tb);
