If you still run into issues after Charles's solution, you might also try selecting the affected text, clearing the styles, and then reapplying whatever style you are using. It's a workaround but has sometimes come in handy for me, although of course is not practical in some situations. You can also record macros to clear styles, apply them, and jump to the next paragraph if you want to do a bunch of them fast, again only if it makes sense for the document at hand and other solutions aren't working.
