The Old Board/Backlog view and the Enhanced Board/Backlog View have different behaviours when we create an issue from the Backlog.

In the Old Board/Backlog view, when we create an Issue from Backlog. We can choose All Issues of Level 0 and above.

However, when we enable the Enhanced Board/Backlog view when we create an Issue from Backlog. We can only choose All Issues of Level 0. This is not documented in the Public Blog for the new changes:

Steps to Reproduce

1. Create a Kanban Board in the company-managed Project.
2. In the Project issue Type Scheme select Issue from Issue Hierarchy Level -1, Level 0, Level 1 and above.
   
   

1. When creating a new Issue from the Old Board Backlog. We can choose All Issues of Level 0 and above.
   
2. Enabled the enhanced Board/Backlog.
3. When creating a new Issue from the Enhanced Board Backlog. We can only choose All Issues of Level 0.
   

Expected Results

The Old Board/Backlog view and the Enhanced Board/Backlog View should list the same issue Type when creating the Issue from the Backlog.

Actual Results

In the Old Board/Backlog view, when we create an Issue from Backlog. We can choose All Issues of Level 0 and above.

However, when we enable the Enhanced Board/Backlog view when we create an Issue from Backlog. We can only choose All Issues of Level 0. **
