All my doodads are gone!

I've been working on my Hordes of Darknes AoS (see sig) for a while now, but I've never had to place a doodad or destructible until now. None of my doodads or destructibles work in-game or in WE! I checked out their paths in the Object Editor, and the path is good, but when I try to manually use the list bar to choose a model, the only one that is available is a list of tree models. Even when I clicked that, the model didn't show. A green cube only appears in-game, but nothing shows in WE.

I'm using WE Unlimited and made a map with all of the extras enables except protection.

PLEASE help me!

Try it in a diff map. Then try in real WE.
