Creeper not wearing or holding items from MCedit filter mobgear but dropped diamond sword.

Creeper not wearing or holding items from MCedit filter mobgear but dropped diamond sword.

I killed a creeper with the filter above and it dropped a diamond sword but it wasn't holding it?

Steps to retrace:
1:find creeper in MCedit.
2:Use filter mob gear and give it diamond sword.
3:Kill it in regular mc and see!
