I'm experiencing strange bugs in the path item on a shape layer.

When I make a two point path (a line) I can no longer go back to edit those points, most of the time. The other times it creates strange affects to other attributes, such as stroke. Stretching the stroke instead of redrawing it at the same width across the path.

I tested in 2017, and initial tests show the expected result, the points are editable and the stroke shows up the right way. But the 2018 version is acting totally different.

A video to show what I'm experiencing is here: https://www.dropbox.com/s/kott8irhd43q5zf/After%20Effects_Line%20Point%20Bug.mov?dl=0
