Bow transmog bug

Hello,

I play on Blackrock and I have the follow bug on my bow transmog :

When i try to transmog my bow, by clicking on "Transmog from inventory", it actually transmogs my main hand weapon (1 hand sword) instead of the bow : i can see the bow icon instead of sword icon , on main hand slot in character info. It also removes the main hand from my character (my sword disapear, and my character attacks with nothing in his main hand).

Some player have same bug as i have, for other people it just works fine...

I have tried to :
- Clear cache
- Clear WTF
- Transmog crossbow and guns instead of bow
- Transmog bow on other character (warrior, and new hunter created for the test)
- Transmog bow on other character on new account.
- Deleted the game, downloaded game from Warmane's link (torrent), and retryed : still same bug.

Any idea plz ? I would really like to mog my fcking bow ^^
