\leq is not an Rd command, so you should be using e.g.
\eqn{X \leq 4}{X \le 4}
if you want to use it. You may find that in your setup \le and \leq give
different glyphs. Standard latex says
/TeX/fptex/texmf/tex/latex/base/fontmath.ltx: \let\le=\leq
where \leq is the glyph name in the CM symbol fonts. MASS is typeset with
\let\le=\leqslant.
