Rails devise cache refreshed at every request

I am using Rails 6, Devise and Redis for caching.
If I run

redis-cli monitor

I see that Rails try to fetch a key and it refresh the cache. Even if I just reload the same page or I change webpage during the same user-logged session. Maybe is it because of utm and referrer field on the user model?
utm/referrer are filled at user signup and they don’t will never change.

This is an issue because I perform a "get"/"set" operation when I just need a "get".

config/application.rb

config.middleware.insert_after ActionDispatch::Static, Rack::Deflater

The problem is not caused by the controller. There is no code.
app/controller/application_controller.rb

class ApplicationController < ActionController::Base
 # It happens even when I remove everything from here and page controller
end

class PagesController < ApplicationController
   def test
     render json: "ok"
   end
end
