I have just installed this mod and couldn’t find any Pineapples. So I made a Creative world and spawned Pineapples, and all it spawned were the stalks. WAILA gave me one of those black & purple boxes when I hovered over the plant.

tropicraft-MC1.10.2-7.0.3.145
Forge 1.10.2 - 12.18.3.2185
Waila-1.7.0-B3_1.9.4
jei_1.10.2-3.14.7.420

Can anyone help?
