I have often seen the issue missing bottom labels on the default
window on my old 13in macbook.  I have always assumed (and I could be
wrong) that this had something to do with the actual dimensions of the
screen.  Recently I switched to a 15in macbook pro and I have never
had this problem (and I never observed it when I connected my 13in to
an external display).  I have various incoherent theories about why
this happens, but I will just state my observation: this only happens
on the native screen of a smaller laptop.
