In Lr, brightness changes when i zoom in

[jenniferp66903188]

As I’m editing, randomly when I zoom in on a pic, it darkens. When I zoom back out to full view it goes back to the brightness level I edited it with. However, I discovered these photos that darkened when I zoomed in are exporting at the darker exposure and not matching the others in the batch, even though they match in Lr when they're full view/zoomed out. This is a cell pic of my screen of a gallery.  It happened at the end of editing this gallery. The ones I circled are how I edited them and the other pics exported darker and don’t match. I have updated LR and restarted my Macbook Pro and its still doing it on random pics, adding to my editing time.

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.
