Hi Damien! I'm trying to get back into some editing today, but my levels adjustment layer is not working correctly. When I select the Levels adjustment (through my shortcut, or by selecting the Image - Adjustments - Levels from the top menu), the Levels adjustment appears and allows me to make changes, but when I select okay it doesn't show up in my layer stack. The changes remain. It's probably something simple but I have been searching and can't find the fix. Thanks!
