Well you said you were asked whether you wanted to replace the existing
index.
:-)
Did you replace it?

I assume it won't let me create a new index while
the old one still exists. So, it does exist.

Why would you assume that? Allow Word to replace the existing one.
Or delete it and create a new one if you want to.

If it still looks a mess, you'd need to tell in what way.
When you insert the index, you can explore the dialog for all the formatting
options.

Or is there's something wrong with the individual entries?
