I have a spline that I previously created in a sketch that I'm having difficulty modifying.  One of the spline handles has a dimension for tangency weighting, but the other handle shows no such dimension.  Despite not having a dimension for tangency weighting I can't change the length of the handle.  It seems fixed.  Additionally, the property manager box won't allow me to reset the spline handle - the box is greyed out.  I click reset all spline handles and that only resets the handle with a dimension.  I don't want to delete the spline and put in a new one because that will mess up a whole ton of downstream sketches and features.  Is this a glitch with no solution or is there a way to gain control of this spline again.  Thank you!
