edit the url in questions list

hello i have a issue with the urls in the questions list
i've edited the slugs so the list is:
http://www.mihaelaursu.ro/ask-me-a-question/
the form:
http://www.mihaelaursu.ro/ask-me-a-question/ask
a question:
http://www.mihaelaursu.ro/ask-me-a-question/question1

they all work well, but:
1. the last one works but redirects to
http://www.mihaelaursu.ro/question/question1/
i do not want that
2. all the links in page are all using default /question so they wrong
what can i do?
