I know about the first option; both dimension have been set to "Not till center", but the top one shows different.
I met that particular matter in other drawings; it has something to do with the representation of the 3D edges in drawing.
The second edge express different.
I wish I knew why the Catia reacts in this way...…!
the inside radius dimension is fine, the extension of the outside dimension is driven by your standard file... check your standard and adjust if necessary.
