I find it interesting that you have no indication of the third setting for the Sorter, while I have a small indication that is fully functional:
This suggests that there's some setting (on our computers, browsers, etc.) that changes how things appear, but I have no idea what it is.
Currently the lack of full-screen means I don't have access to all of my upgrades any more. The page ends at Steel seller and I can't find a way to scroll it any lower. The only way to see the remaining upgrades is to move the game 1) to a different browser (Chrome, I normally use Firefox), 2) on a bigger monitor, and 3) full screen. If I only do two of these things, it doesn't work.
