Duplicating Notes Section - issue

I am currently facing the same problem. I have also duplicated all the necessary files and given them a new name. However, the corresponding new posts are not displayed. Do I also have to create a new variable and where can I do this?

I would like to have 3 pages that all work with the same behavior.

They are different artists
that appear under different labels

Label 1 / Artist…
Label 2 / Artist…
Label 3 / Artist…

Where do I have to define the variable.
$Label1 as $Artist

I have also tried to use Notes as a template in site.yml, but unfortunately without success.
