Missing Reply pages

Hi

This is a really good plugin. However, I noticed that in missing reply there is no next page. For example it says “Missing Reply (100)” I can only see about 20 and there is no “Next Page” like when you view “All comments”.. I disabled all plugins and so far no conflict.. Any ideas? Thanks!
