Guild Wars 2

Im having a problem that makes my use of the BL Trading Post a little annoying.
Because it those not let my write the item name in the text box for the search.
Every-time i want to buy a specific item like 4 example: If want to buy a “explorer armor”
i have to do a advance search withe out the name and browse through all the armor until i get to the explorer armor. I have tried every trick except uninstall the game and install again. It only happens in the Trading Post, in the tab “sell on trading post” the search box works.
A little help PLZ .
