My account icon broken

Hello all,

I am having trouble with my My Account Icon in my main menu. I have updated the design of the icon, and it seems that it is updated when I am logged into wordpress but when I check it in an incognito window it is not updated. I have purged my site cache and my browser caches but it does not seem to work. I have included some screenshots below. Any assistance with this matter would be greatly appreciated. Thank you.
