Before I can approve, please replace all the following doodad models in you pack with the fixed ones. All of those were not selectable in world editor so I had to fix them.
Next time of course you can do it yourself, but I had to be sure I even know how to do it myself.
First of all always check if the model is selectable in World Editor after you're done with it.
If it isn't, basically you have to save the model as MDL and go to each geoset (ctrl=f search for "geoset") and edit those marked values with what I have. The MeterialID will be unique for each geoset so that much be changed for each geoset (before you edit you will see what ID it had).
Below is the zip with all fixed doodads, replace and I can approve.
