Sites reappear after deleting...

Hi 
I'm very new to ServiceDesk so this is probably be a something very easy to sort..

Under Sites in the Admin page i have 85 different sites listed which have our department names listed, we only have 1 site. When I delete the sites they reappear the following day.

I'm guessing this is related to the Active Directory import but I can't see a setting to ignore Sites.

Any pointer would be great fully received...
