Agricraft crossbreading

I added agricraft to a modpack and wanted to do some crossbreading.
Started a pattern like this:
O
ONO
O

O being the vanilla wheat seeds in a crop
N being a empty double crop

Everything is lightened up and irrigated

For some reason no crossbreaded seed is appearing. I tried to crossbread some other seeds, but it wont work.
Any ideas why this is happening?
