Redmine

After create a new issue, I can see the priority on the issue screen.

When I click the edit button, I don't see any way to change the Priority field. That field doesn't even appear in the edit panel. Further, I cannot set Priority on main issue list item menu.

Experimenting seems to indicate that the problem is related to sub-tasks. When an issue has sub-issues, you cannot edit the priority. Delete the sub-issues, the priority field appears on the edit panel.
