How do I fill my composition with Simple Choker?

Good

Good day everyone

I've encountered a problem where I can't stretch my composition to make it fill my screen while Simple Choker is applied on a composition.

Open the bottom left Magnification Ratio options in the Comp panel and set it to Fit or Fit up to 200%, then set the Comp Panel Resolution options and set it to Auto.
