BadgeOS "Add step" is not working! :(

Hello! I am new using BadgeOS (amazing let me say!!) but I am having some issues while editing my achievement types ?? When I want the achievement to be earned by completing steps and go to the “Required steps” section, nothing happens when I click “Add step” Why is this? Please help me! I don’t know if this happens to other users as well. I really appreciate the help of you guys!!
