when there is no object it means world editor cant read the objects from the object folder, if u are talking about lorencia u cant do much cus lorencia is the first and oldest map coded differently, u must find other lorencia map (files) from just another client data/world1 and object1 and open it with world editor and see if u can see objects, u will find the lorencia thats working from ppl who release skins for lorencia, those ones u can view objects and everything.
if u are talking about new maps.. thats normal cus depends on .bmd and what maps
