For information: I am currently both Org and Site Administrator.
I was going to configure workflows and screen schemes for my projects. However, looking at the "Wheel" for settings the "Jira Settings" does not Appear. Seen below is a screenshot of what appears when I go to the Settings section.

Furthermore, when I go to Settings in the Sandbox I see the specific section I am looking for as seen in the picture below.

Can someone please help me resolve this? I need to edit workflows schemes and screen schemes.
