Problem, regarding titles

Hi, the stuff that google is displaying is rather messed up, and im unsure why this is happening, would be greatful if someone can clear it up? my site is “crunchyanime.com”, if i were to type in google “site:crunchyanime.com” i would see what pages google index’s however there are hundreds of duplicated TITLES. Google displays the correct permalink however the titles are all wrong, why is this?

For example google title “Gundam 00 Second Season Episode 24 | Crunchy Anime” but the permalink is this “www.crunchyanime.com/bleach-episode-2”, am i missing something? should it not be “bleach episode 2”? title should be as the permalink? i checked the post that i made and all it seems to be in order ..

Another curious thing i saw, for example if i go on any section, then view the video as a single post the title of the post (im using mozilla and i can see it in the browser) is of another post which is more recent, could anyone help me clear this up please?

Could i have to do with the sitemap? im using the google sitemap plugin
