unanswered Attack Category in XYORAS

I've been playing around with the field-effect moves using Poke3DS, I noticed that when I change an 'other' category move to be physical or special, copying over every other field from an existing move, [experimenting making Flash have Dazzling Gleam's properties]:

If I use that modified Flash in battle:

• If the move would KO the target, the target is KOed, but no HP bar animation is shown.
  
• If the move would not KO the target, the move animation plays as normal, but nothing happens at all, turn proceeds as normal.
  
• A similar experiment, Parting Shot -> Teleport, always results in the 'move failed' message
  

I suspect that there might be some other set of flags somewhere that Poke3DS is unaware of... Could anyone give me some pointers as to where to proceed in finding them?
