Does anyone have a problem backing out of a site using edge

When I'm on different sites that I usually use with Edge , when I log out of that site using the top left arrow on the screen only backs out a few times then the arrow grays out so I can't back all the way out. The only way I can is to exit the internet. Which I know you are not suppose to do. My PC is new but I had the same problem with my previous PC using Edge.
