Lens correction control point behavior

I am trying to figure out if this is expected or if I can make a change so that the post 2014 version of Hugin works like the pre-2014 version when doing lens correction.

In the old version as you would place control points they would only appear on one side of the image (left side for the left image and right side for the right images) as seen here in this screenshot - https://www.screencast.com/t/HSWzBkoPB

In the post 2014 new version of Hugin you get these lines that go across the entire image on both sides as seen here - https://www.screencast.com/t/RVRV1srhI2

Whenever I put all the control points down I am able to optimize and get a set of lens correction numbers but they are always way off and still don't fully correct the image.

Can someone help with this please?
