Duplicating lead when killing a mob using a Sword with Looting

Seems to have found an issue. Steps to replicate below:

1. Use lead on any mob
2. Tap on a fence (only appears to happen when mob was tied to a post)
3. Kill mob with a Sword with looting enchantment.
4. Drops with 2 leads

Device i was using was Asus Zenfone 2
Looks like the lead is getting affected by the looting enchantment somehow.
