How access section B

Sorry if this is inappropriate. Just getting started and when I’m in scales mode in section A, how to i get section B to appear, The only way I can is to go into song mode, but then I’m in a different scale than I want to be. And if I try to change the scale in section A, section B doesn’t change
section A Section B different

Click on the Scale. Section B will appear.

Thank you. I feel like an idiot. Gordon
