Why do sub task controls disappear for some JIRA issues?

[Aram Ghanimian]

One of my users claims that they have to delete and recreate issues when they don't see their sub task controls on the main issue. When I saw their screen shot, I immediately tought that it was a workflow problem. Does this happen to anyone else?

I am no JIRA architect, so please let me know if this is too generic.

How can I dig deeper to find out what's happening?

That sounds wrong, although there is a hard way to do it in the workflow.

I think you need to replicate the behaviour to confirm it, then look at the properties on each status where the sub-task controls are not there.

Would it help to share the screen shot sent to me? And how do I check the properties of each status?
