Q&A - theme shows different title

My theme (RT-18) shows post's title on the header, but it won't match the Q&A titles on the main pages. Is it possible to check if it's a q&a page and hide or change the title ?
On "Ask a Question" it shows the last blog post of the site
http://smartchoose.info/lib2/questions/ask
one the main page it shows the last question's title:
