The active view on the left shows the sketched profile (a circle) and the profile label (A). The detail view on the right shows the detail view label, which displays the profile label (A) and the scale (1:1).
When you insert ordinate dimensions in parent views, the dimensions continue in detail views. The detail view uses the existing 0 point in the parent view. Conversely, when you insert ordinate dimensions in detail views and apply ordinate dimensions in parent views, the parent view uses the 0 point from the detail view.
