I can't view my recently imported files in the new version of Lightroom. The import modules says they are imported, but I can't view them in my library.
For existing photos, select all your images in Grid view, and then click the Reset All button in the Quick Develop panel. Then click the Auto Tone button to properly apply this feature.
To prevent this from occuring in the future, choose Lightroom > Preferences > Presets (Mac OS) or Edit > Preferences > Presets (Windows). Uncheck Apply auto tone adjustments.
Hope it helps.
