It appears that your Word files are badly corrupted.
I would look to finalizing the Track Changes function within
Word, where I would ensure that all changes have been accepted or
rejected. That may or may not help.
I would also question that "Inline" style issue, where I
believe RH is seeing years' worth of manual, inline formatting that
was done in Word
in addition to the style selection, and attempting to deal
with it.
To experiment, I would Select All, Copy the entire content in
one of these Word files, then Paste it into Notepad. Then remove
any extraneous line breaks until the paragraph formatting looks
right, and Select All, Copy again. Then in RH, create a new topic,
paste the Notepad-copied content, and assign the proper styles. I
suspect that you'll be pleased with the result.
Good luck,
Leon
