There are two separate issues here:

For the unexpected role issue, we have something come up in the next release: https://microsoft.github.io/autogen/docs/tutorial/conversation-patterns#changing-the-select-speaker-role-name.

Could you please also update your PR description with your code, and your Claude set up, are you using Anthropic API or proxy?

For your issue with function call, it is hard to see the cause without your code.

Hey I've improved my claude example with system message with a new PR. The claude API without system message is already avaliable following this notebook. Looking forward to your feedbacks!

please try to reproduce with autogen 0.4.5 or later and reopen if needed
