Problem with drops & Equipment

I'm currently having issues with the Mythicmobs equipment and drops system. This is my code:
Wraith:
Type: BAT
Display: '&4Wraith'
Health: 15
Damage: 5
Skills:
- summon{type=Wisp;amount=3;radius=5} @NearestPlayer{r=10} ~onTimer:300
AITargetSelectors:
- 0 clear
- 1 players
Equipment:
- blaze_rod:1
- WraithSkull:4
Drops:
- WraithSkull 1 0.1
- gold_ingot 1-3 1
Disguise:
Type: SKELETON
However, the equipment does not appear on the disguise and the drops don't...
