This has just happened today. I only see Story Points field in the detail of Story, but for others (Task, sub-task, bug) I don't see Story Points field.
In the past (I mean just yesterday and before), I still see Story Points field in all issue types. I didn't make any change, it is like auto happens
1. This is Issue layer: 
2. This is User Story detail:

3. This is Task detail:
