I am having an issue with saving gradients in the gradient editor (PS CC).
I select the colors and settings I want to save, click on NEW and name it. It appears in the Preset list and the colors/settings are correct. Unfortunately, the moment I get out of the editor window and continue working if change either foreground or background color it changes the colors in the gradient I created. Even when I am changing colors using brushes, it changes the colors of the saved gradient. This happens to all of the gradients I create on every document on every library. It effectively makes creating gradients and saving them completely useless because they do not retain the colors I have selected.
Could you please let us know which version of Photoshop are you using & which operating system are you working on?
Also, could you try resetting the preferences of Photoshop & let us know if it helps: Preferences in Photoshop
