Hi,
You encountered this issue as the keywords in both ad groups are actually the same keyword with the same ID. This is not related to the API version and also happens if you create the keywords via the UI. I would check with the general AdWords support for more details, but it short: "You absolutely should not use the precise same keyword in more than one Ad Group or more than one campaign for a single domain name covering a single geographically targeted area" ( http://www.google.com/support/forum/p/AdWords/thread?tid=653e1b35aa76624b).
