Multi Site Setup: Google uses Metainfo from another domain on CMS

hi folks,

i am haveing a hard time geting google to index the correct title and description for a homepage.

let me tell you about the setup:
> typo3 cms with multiple instances on different domains (all different content)
> domain1.com shows the correct title and description
> domain2.com shows the title and description from domain1.com in serps but when you click on the link, it is domain2.com (so correct link)
> when you put in domain1.com the homepage gets redirected to domain1.com/en (for language settings)

i tried to have google reindex the homepage, made a sitemap, used webmaster tools but so far, the homepage has not been reindexed although google spiders visit the page frequently.

what can i do to tell google to index the site again? shall i remove the homepage using webmaster tools?

please let me know what i can do.

thanks,

d

please let me know

no one can help me out?
