Camera Raw Filter result doesn't match Preview

[Elvis30363879iisb]

When I run Camera Raw Filter on a selection to adjust the highlights and shadows, for example, the preview looks great. But when I accept, the result always comes out with excessive brightness. 
Only since the early June Beta update.

Hi @Elvis30363879iisb 

Try resetting Prefs for the Beta:

/Users/yourname/Library/Preferences/Adobe\ Photoshop\ \(Beta\)\ Settings 

Launch BETA Photoshop While Pressing The Keyboard Shortcut

With Photoshop closed, press and hold Shift+Ctrl+Alt (Win) / Shift+Command+Option (Mac) on your keyboard and then Launch Photoshop the way you normally would.
