Recent login activity

Whenever I log into blizzard or battle.net in my account under recent login activity it shows u when u log into into either the website or the desktop app. Now I have changed my password just in case and logged out of all devices. It shows the wrong city when I log in. But blizzard has told me that on their end it does show the correct city. So therefor this is a glitch or bug I would like to get fixed please.
