I would suggest you to please remove the Previews File of the Catalog, it will be in the same location of the Catalog, and will be <Lightroom Catalog Name> Previews.lrdata.
Please make sure Lightroom is closed while you are renaming or deleting this file, and then open Lightroom and see if it works.
In case the above does not help, please try and check the Monitor Profile of the computer : http://www.lightroomqueen.com/articles-page/how-do-i-change-my-monitor-profile-to-check-wh ether-its-corrupted/
While this could be a problem with the catalog previews, I'd be very surprised if it is a problem with the display profile.
A couple of other things to try:
- In all three screenshots, the Adjustment Brush is active. Try closing it by clicking Done in the lower-right corner or Close in the adjustment-brush panel. Then apply the presets.
- Uncheck the option Preferences > Performance > Use Graphics Processor. LR CC 2015 / 6 sometimes doesn't update the main image display properly when you apply presets and the graphics processor is enabled: Lightroom SDK: photo:applyDevelopPreset() doesn't update Develop display when GPU enabled.
Thank you for your help, @Tanuj Sandal. I removed the previews file as you suggested, then opened lightroom, and the same thing happened with those very same 3 presets. And then I noticed that the files went right back into the folder that I'd just deleted them from. This is really annoying. I tried to check the monitor thing out, but everything's good there. I don't know what the issue is.
Do Help > System Info -- what's the exact version of LR you're running?

That's normal -- the file stores the previews of your images, and when you delete it, LR recomputes the previews. Very infrequently, the file will get corrupted, which is why Tanuj suggested deleting it.
You could try updating manually to 6.1.1, which fixes a number of serious bugs. I don't recall seeing any mention of preset-related bugs being fixed, but it's worth a try.
Definitely do not update to the very latest release, 6.2.1, which has been a disaster for many users, and for which Adobe has apologized. Instead, manually download the update for 6.1.1 (the last stable release) from here: Download Photoshop Lightroom.
