Thanks for your posting. You can find a quick overview on possible locations and positions here:
The location/position is determined by the field type and entity the field is for. For cases, fields are displayed either in the blue area at the top of the screen or at the bottom. Small/compact fields are shown in the top area and large fields (fields of type Text or Steps) are shown at the bottom.
Likewise, for test results, large fields are displayed on the left and small/compact fields on shown on the right of the dialog.
I hope this helps!
