Hi there,
I'm having a couple of issues in setting things up.
1. When a new Sub-Task is created under a Story, the 'Time Spent' field is mandatory. How do I set this as non-mandatory? It's a new sub-task so no time has been spent on it. I've tried changing in the field configuration but no luck.
2. I want to add the 'Original Estimate' field to the Sub-Task form. I cannot find this field on the Issue Layout or Configure Screen pages. How do I do this?
3. When I change the layout of my issue screen, it's not reflected in real time. (Screenshots below)


Any ideas?
4. Do all issue types have to have the same fields and layout? If not, how can I change them?
Thanks in advance
