Single Role Creation - Issue during the Generate Roles step!

Hello all!

I´m configuring BRM using the default workflow. During my role creation test I faced a issue during the "Generate Roles" step. Simply the button "Generate" is disabled so I can´t move forward.

Please check the printscreen:

Someone knows how to handle this? Additionaly I noticed the role was created during the "Maintain Authorizations" step, even before the "Request Approval" has been finished. That´s because step "Maintain Authorizations" opens PFCG on the backend for me to add the authorizations and automatically creates the role. This is normal? If not, what am I doing wrong?

Thanks in advance,

Pedro
