I tried seeing if it needs _ or none but neither works and I had a drop which says drops: 'rotten flesh:5:75' why is this?

EDIT: Apparantly all items are supposed to have percentage

Still have a problem with cooked and raw porkchop how do i say it?

'raw porkchop:5:75' 'cooked porkchop:5:75'

EDIT: Its apparantly pork and grilled pork you guys need to change the names to the one in minecraft wiki for easier configuration
