I understand now why you were forced to accept the original tangency; it was already there in a finished part needing redesign. I just duplicated the button using a Revolved feature to create the top dome portion. If I delete the tangency constraint in the spline sketch, I can then add an angle that allows me to control the shape. I'm puzzled, though, that you have two splines in your sketch; is this not a revolved feature? Have a feeling I'm still missing some part of your problem?

Also want to return to my original question concerning what you expect to happen. I don't agree that the system "should" return the shape to the "one on the left". The original shape of the 2-point spline, before putting the top central 90 degree dimension in place was a straight line. After adding the angle dimension the other end remains tangent to a line between the end points, but as soon as the tangency is added, any straight line reference between the end points disappears; there is no particular reason for the constrained end to move anywhere else once you remove the tangency constraint.
