It doesn't save the changes in advanced settings

[Juan Simón]

I change some advanced settings like "Enable phishing and malware protection", "Send a ‘Do Not Track’ request with your browsing traffic",... but when I close the tab it doesn't save the changes.
In console it shows this:
[13255:13255:0129/113840:ERROR:CONSOLE(2473)] "Uncaught TypeError: Cannot read property 'uncommitted' of null", source: chrome://settings-frame/options_bundle.js (2473)
