How to assign Layout Editor and Proofreaders?

We are trying to register Layout Editor and Proofreaders. However, the assign button doesn’t appear in my OJS, as you can see in the image below:

I’ve run through necessary steps of the Copyeditor and now I can’t go to the next step, because I can’t assign these roles.
Also, both Proofreader and Layout Editor doesn’t appear in the roles Section:

What could this be? Did I miss something or there’s an error in my OJS?

Hi @sienp2016,

Check Journal Setup, step 4.

Thank you so much! I picked this project just in the middle, so I didin’t know about step 4. In case anyone is reading this topic and looking for help, here’s step 4: PKPSchool: OJS for Journal Managers: Setup Step 4 - YouTube

My thanks to the OJS support team, you guys are amazing!
