Now if you have installed the change as mentioned by Chetan, you will see that via Home page the TourShowcase module published shows the correct page title; which it does off-course.
Next when you check the same tour via Tour menu page as a component then you don't see the correct page title, in that case please let us know your menu type.
Because if the menu type is Tours you will see the correct page title but if the menu type is Tour Types then it's a bit incorrect you will only see the page title of the first tour in the list.
So please confirm your menu type here and clear the cache and then check because looking at your website, it seems you haven't installed the change.
