Changing citizenship for US Tax Forms

When submiting my W-8BEN (US Tax Forms) my citizenship is automatically set to Australia. This is incorrect as my citizenship is in Germany, but the issue is that I can not change the citizenship section because it greyed out and I can not select it. Can someone please provide me with advice as to how I can change my citizenship.

Thank you


Same issue here.

Hey folks, Did any one of you managed to get this resolved? I am stuck in a similar situation.
