Issue when logged in

Hello
MY website’s main currency is in AED, and i have added oman, bahrain and other Gcc countries zones as well including saudi arabia.
But when ever i logged in wordpress dashboard, the front currency automatically changes to Saudi riyal. When i logout wordpress dashboard, it automatically changes back to AED. When i deleted the Zone saudi arabia, there is no issues. This problem persist only whenevr i add Saudi arabia currency zone.
