Adjustments Not Working

Just uploaded photos taken on my Sony DSLR camera. When I go to edit the photo, I can rotate, crop, and use filters, but neither enhance nor adjustments do anything. I can pull up the sliders and physically change them, but the image doesn't change at all. I had no issues making adjustments back in the Aperture/pre OS X Photos days. Anyone have any ideas?
