Hard Mix not exporting

This is a binary image that consists of either black or white pixels. To properly see that pixel structure on screen, you need to view at 100%. 

100% has nothing to do with size. It means one image pixel is represented by exactly one physical screen pixel.

You're viewing at 11.4 and 12.5 % zoom. That means 7100 pixels in the image are downsampled to around 750 pixels on screen. That's a lot of data that needs to be interpolated, and in that process, crisp black/white edges inevitably get replaced with fuzzy gray pixels.

Different screen resampling algorithms will put very different results up on screen.

If you view these two at 100%, you will see that they are identical and it exports correctly.

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
