Hello Jadian. You may have already figured this out but you have the ability while in the Medical History Summary to select the shading under the Custumization options at the top of the screen. It's the little box with a line through [-] that is next to the Help [?] box at the top right of the screen. Move to the word Show. I am using v 2.1.10. Also, there is no Custumization option for shading in the Medications Summary screen.
