PRIVACY ISSUE

Recently i noticed that all my searches are being saved and shown even if i disabled the save searches feature, i thought it was just affecting my current device,but when i checked with my other mobile devices at home, it has the same problem, saving searches even if the option is set to do not save searches, also i tried using the search with and without logging in to the google account,the same issue persists.

VERSION:

Chrome Version: [63.0.3236.6] + [dev]
Operating System: [Android 7.1,5.1]

This affects my privacy greatly as my searches are only meant to be seen by me.
