I added 2 custom fields that are user selector fields (Reviewer and Tester). I use them in a post function to switch the users as the task progresses through my workflow. When I (or any of the other developers) create a ticket the 2 custom fields are standard drop down user selectors and available. Everything works as expected.
Except for the other admin. For him, the fields show up as locked for him. And only him.
He told me the only plugins he's running are Slack and Github, same as me. When he creates a ticket I can add the reviewer and tester. He's adding a new ticket the same way I do.
What can I check/how can I make these fields available for this one "problem child" user?
