Guild Wars 2

No one in my guild seem to have this problem and by judging the lack of replys, neither does anyone else.

Does anyone have any idea what could be the cause of this? I’m really at loss here.
For example, does corrupted or misinstalled gw2.dat file be to blame?

Here’s a picture (and yes, the mouse is hovering over the icon)

There is currently no item previewing at the trading post. And no, I don’t mean wearing it for preview. One can see nothing but the name, no stats, no damage range/ armor rating, nothing.
I hope this is an actual bug and not a feature as one cannot possibly expect players to memorise all the possible rune names, stats, etc.
