strange bug on warrior macro

Hello! Sorry for my english! i have a wierd problem with making a macro for cast defensive stance, equip 1 hand weapon and shield. Dont ask me why i need that. i am pretty sure that my macros are working. Tested from friends. /Cast defensive stance /equip 1h weapon/equip shield...i have tryed with /equipslot 16/17. i also tryed with casting def stance before and after equipment. the problem is that when i use macro, it casts def stance, equip 1h weapon, equip shield and after half a second SHIELD IS REMOVED!. i made a macro ONLY to equip weapon and shield, but after i manually change stance ( without macro), shield is removed again. i am pretty sure that i write macros correctly. i started to think that its an account bug. i need suggestions how to fix this. Thanks in advance!

i could fix this bug alone.........it was Outfitter addon wich was causing the bug. removed it and all is fine now.
