Can not see Update Column in Approvals Business Analyst Responsibility

Hi,I am implementing AME for different Operating Units, because of that, I created different responsibilities and when I created the Grants, I assigned the Operating Unit to every responsibility. But after that, I can not see the Update column in the responsibility, and I can not do the setup.

I am uploading a screen shot with the example.

Thank you so much for your help.
Best Regards,
Vanessa
