Items without stats?

Hi. I just get the lvl 80 on Deathwing and bought some little better gear from AH. Hall of items i bought is now without stats, like all the stamina and int dissappear from them. When i was buying it on AH it had stats and for a while they were working. Now after few log in and outs half of my EQ is with armor only. When i compare this items using shift it shows how stats would change and it is correct but when i wear them it shows no change to stats, just only armor. Its a server or my client bug. What to do with it?

I'm having this problem too on Ragnaros.

Same problem on Icecrown.
