Forum:ME3 helmet is not off during conversation?

My Shepard currently is wearing Cerberus Nightmare Armor. I have set the helmet option to "Off in conversation" but it doesn't seem to work anymore? I mean, it used to but recently it suddenly just appear to be like that. The only changes I've made is using Gibbed save editor to change storyline and unlock all armors. A few weeks ago I made some changes but not affiliating to armors in coalesced.bin too but it never raise any issues before. Anyone know the fix? I know I can set the armor helmet-less using coalesced.bin but I want the helmet to be off only in conversations, not in battle.
