[pl] logout is not translated in system menu

Sorry in advance if I picked the wrong component, I am referring to system menu.

XFCE, Polish localization.

When you open this menu you will see "Logout" entry is NOT translated into Polish. When you click on this item, you will see logout dialog, there are several choices, among other is logout, this time it IS translated into Polish.

So it does not have to be translation missing, maybe some binding?
