I have seen a few forum posts regarding this, but none really answer my question.
I am trying to use Story Points for a task, but I am currently unable to assign them.
I have checked the following:

As you see this is enabled.
Under space settings though under fields, I can see Story Points isn't assigned to any screens. I'm assuming this is the issue. But I don't see anyway of adjusting this.

Some help would be appreciated
Thanks
