Harmony Essentials Resize Reference Image

I was just trying to resize a PNG that was 1920x1080 in my 1920x1080 canvas. For some reason Harmony brought it in at a size smaller than the canvas(why??). I couldn’t figure out how to resize it until I twirled down the layer options and had to guess at what relative scale it was to the canvas in the X and Y scales, is this really the only way to size an image in Essentials? Are all versions of Harmony like this? Why can’t i just select the image and transform it?
