Presets Showing Up Dark

[kaytic72781758]

I have no idea what is going on here, I have been editing for a few hours and all of a sudden I clicked over to a new image and it turned the whole thing dark. Ctrl-Z only deselected the image and then it went back to normal. But when I clicked on another image it happened again. I tried resetting the image and applying my preset (that is not one I have to make big adjustments from) and even when I apply the preset it goes WAY dark. Not sure what is happening or if I've done something to make this happen - hoping someone can help.

I even just tried re-downloading the original preset and it's still showing up SUPER dark so I didn't change the preset settings - it's something within lightroom itself.

When exporting, it appears to export correctly - so it seems to just be the display. Sorry for the million updates, really hoping someone can help me sort this out.
