There is no command for drawing borders below -- so none were drawn.
Use \hline as you did elsewhere, or \cline{2-4} to decorate only the
\multicolumn created cell. I have no idea why the right border was
not drawn.

You  could give up the vertical borders and increment the space between
columns. (I believe this is the recommended way to typeset tables, but I
am not an expert.)

BTW, Any particular reason why the last argument of \multicolumn is
delimited by blanks (\ ) instead of the standard curly braces ({})? This
is not the cause for the problem, but could become a cause for other
problems in the future.

HTH, Itay
