Problem with the new user review system

I am trying to add a review, where I wrote a list like this:

- argument 1

- argument 2

etc.

Everything else gets added, but all the points with " - " before it are removed? Do I need to list it with 1. 2. or a) b) ?

And second the reviews are sorted to "by helpfulness" I would like to sort it chronologically or by "hated it" "loved it", how is that possible now? Thanks for any help
