Per 
https://learn.microsoft.com/en-us/windows/win32/api/winuser/ns-winuser-menuiteminfoa

The MFT_BITMAP, MFT_SEPARATOR, and MFT_STRING values cannot be combined with one another. 
(nb MIIM is the replacement name for MFT but the same applies)

I suspect you mean to be setting
HBITMAP   hbmpChecked;
and/or
  HBITMAP   hbmpUnchecked;

not
 HBITMAP   hbmpItem;
which is used to display a bitmap instead of a text string label.

Also you aren't clearing the fMask / resetting it when using the entries without a bitmap
I have no idea how much all of this can confuse the GDI API.
