Some service desk issues are having a problem where the sub-category for a custom field is not displaying. Both are requests that were sent in via email and i have confirmed them both to be using the same issue view, issue type, and layout. There is only 1 custom field with that name and is set to all issue types in the context for that project.
Selecting one of the options will have only the main category appear and no option to select a sub-category.
