I've created a new Issue Type with it's own workflow, screen scheme, etc. I can see this issue type within the project settings of the Service Desk Project I am attempting to work in. However, when I attempt to create a new Request Type with this Issue Type, the Issue Type is unavailable in the drop down menu. I have created two new Issue Types with similar methods and have successfully added them as Request Types so I don't know why this third issue type is causing issues. If anyone could provide me with any help that would be much appreciated.
