Questions don't appear

I’ve a problem with DW Q&A plugin. i configurated this plugin and i’ve just tried to make a question but it doesn’t appear in dwqa-questions page. You can see the problem here https://www.biochronicles.it/dwqa-questions/
There is a question in this page but it doesn’t appeat and you can’t choose it. Why?
I see that the question appear in this page https://www.biochronicles.it/question/
but this isn’t the page that i’ve put in the menu of my blog. This page doesn’t exist in “Pages menu”. How can i solve this problem?
I’ve thought to use a redirect 301 but i don’t think that it is the right way to solve the problem.
Thanks for help,

Andrea
