Pixel values within After Effects not making sense
I can't seem to figure out what is going wrong here. I am trying to edit shape dimensions by pixel value and the placement and size within my composition doesn't seem to line up with the values I've set.
I'm finding it hard to fully explain so I'll include images as well.

So here I have a 1920px x 1080px composition. I've created a shape and set its width to 1920px, and its x position to 0px. I'm confused as to why this block doesn't cover the entire length of my composition but instead ends at around the 1860-1865px.
I feel like there's something very basic I'm missing here, any help is appreciated.
