I have selected several fields to be displayed on the final workflow screen, but for some reason they appear to be absent:


Following fields are missing: 'Resolution', 'Fix Version/s', 'Assignee', 'Log Work'). Strange thing is that when I add any other field, it will be displayed on the final screen. I checked field configurations and it turns out that all those fields are visible.
What might cause JIRA to behave that way?
