when im in the auctionhouse i can buy sell or bid, but every time i do the message keeps popping up and i dont see the change in the aucionhouse

for example if i buy something it gives the message the item is still inlisted on my screen but i did buy it and its in the mail box
i need to refresh the auction page and then i can continue.

is there something wrong with my files ? (seeing as it has been this way from the start of 5.4.8 update)

thank u in advanced for the help :)
