The glissando can often become so short it
is invisible, as happens here.  It's length
can be overriden, but it's a bit messy.  The
method is explained in section 5.4.6 of the
Notation Reference, and I've given an example
below.

You need to add as many hidden voices as the
number of notes in the chord less 1.

You have to set the beams manually, which
means the start and end notes of the beam
must be in the same voice, hence the spacer
notes in the example below.

Below is one approach to your problem.  You
will have to ignore warnings about clashing
note columns due to the hidden notes.  I've
also increased the thickness of the gliss,
and the length is probably too long - you
can easily adjust these.
