1. I edited the 'Default Screen'.
A Date Picker of 'Start Date' was added.
Version Pickers of 'Affects Version/s' and 'Fix Version/s' were deleted.
A Version Picker of 'Milestone' was added.
2. A new UI is displayed in the 'Create Issue' screen.

3. But unwanted fields of 'Affects Version/s' and 'Fix Version/s' are displayed in the 'Issue' screen.
A newly added field of 'Milestone' is not displayed in the upper area of 'Details'.
A newly added field of 'Start Date' is not displayed at a wanted position.
Please tell me how to do these modifications.
