Curve Tri Fill brush issue

I’m trying to edut curve form after creating it. But as I try to draw any part of the curve (green point in attached example) tips (red points) are always moving along with my editing. But in official video tips are fixed. How could I fix those tips and edit curve without moving them?

Got it! Solution is Stroke/Curve/Bend start+bend end +elastic
