Status bar disappears when I use the drop-down menu

[Haex]

The status bar works fine in every app o tried and on home screen, but when I pull down the drop menu, the status bar disappears and will appear again if I enter in some menu or open an app.

The status bar shouldn't disappear if I use the drop-down menu.
