Disappearance of the corrector of the sail
I'm guessing that you mean Dehaze.
Dehaze was introduced in Lightroom 2015.1, and for local adjustments in 2015.2.
You have version 2015.0 installed, so you need to update - the latest version is 2015.10.1.
Use the CC Desktop app or Help > Updates to update.
If it doesn't work, download the latest version from here: Download Photoshop Lightroom
Your update will be under Adobe Photoshop Lightroom 6
Thank you for the answer. I indeed mean dehaze, mistake from the automatic translation.
Both CC Deskop app and Updates from LR said there is no update available. When I click on your link, I cannot download anything, do you know why? I don't have serial number since I subscribed from CC and I am logged in.
You have to click > Adobe Photoshop Lightroom 6 - it will expand and show you the downloads.
Here is a direct link for the 2015.10.1 update for Mac: http://swupdl.adobe.com/updates/oobe/aam20/mac/AdobeLightroom-6.0/6.10.1/setup.dmg

It was painfull, but it finally works!
Thank you very much Per for your help!
