Editing photos

Hi, I'm om High Sierra Beta 3, and have great trouble in editing pictures manually. Clicking Curves activates smome automatic action, it seems. But i would like to adjust as I thing is best. Clicking White balance used to give med an opportunity to decide on the white balance. Not any more.

Anybody else with the same experience? Or have I missed som essential key when trying to edit?

I am writing an app in Xcode 9 and Swift 4 which allows a user to take a photo with their device camera or to select a photo from their image library. I have the permissions allowed in the plist file so the user has access to the camera and the photo library, however, they cannot edit the photos from within the app, though they can take an image with the device camera outside of the app and edit it as well as grab a photo from the photo library outside of the app and edit it. I have searched far and wide , in StackOverflow, the developers forums, youtube, and generalized Google searches without finding anything. Any suggestions would be greatly appreciated. Thanks !

Tom
