I see whst you mean now. I wasn't looking at the recent proposals section on the homepage.

What you are seeing is one cover letter and one commit from the same proposal but listed separately.

There are two problems uncovered here:

1) 'recent proposals' should just show the proposal root and not each each commit.

2) links to a commit (or a reply for that matter) should take you to the proposal page with the specific commit / reply highlighted.

I'll look onto this next week.
