Arrow-key bugs + inaccurate color profile

I'm on version 26.3 (Mac), and when I double-click a layer and attempt to preview saved custom styles (layer style -> styles), I have to click each one via mouse because the arrow keys don't respond. Also, when I attempt to change the gloss contour under "bevel & emboss," tapping right or left with the arrow keys always skips the adjacent styles (e.g., If there are 7 contour styles and you start at Style 1, clicking the right arrow will select styles 3, 5, and 7 while skipping 2,4, and 6.) 

Additionally, I'm not sure if this is specific to my monitor  (Samsung LU28R55) or not, but I typically use Photoshop on my Cintiq and have a duplicate window open on the monitor for previewing. Whenever I wake the computer from idling though, the duplicate image on my Samsung always appears washed, like it changed profiles for some reason. But if I then exit the window and create a new duplicate, the colors appear normal again. 

Anyway, nothing major. Just figured I'd give a heads-up.
