There's no telling how much style formatting was done in the
Word file (all of which Word seems to retain), thereby causing
issues upon conversion into any other app, not just RH.
You might take a look at the underlying RH TrueCode; it'll be
a revelation, I'd bet! If you can't figure out the problem that
way, you might try attaching all the code for one small list
(starting OL tag to ending OL tag), along with the style code from
the CSS style sheet, using the Attach Code button below. Someone
here should be able to spot something amiss.
Good luck,
Leon
