Plugin doesnt for all the time

Hello,

i had problem with all in one seo pack. i use different title & description for all my pages. but it sometimes doesnt show up in google search.

i mean, i see different title & description when i check google search results

here is example:

1. this is what i wrote on seo
2. search engine results

now im thinking whats the problem ? when i added 10 new contents 5 of them like this, in other ones plugin works just fine.

thanks for helping
