Could you screen your 3ds max with one of the object where collision doesn't work? Only the naming in the scene is supposed to change the collision of an object.
Be sure to have the "WLLCONC" as prefix, for example "WLLCONC_concretewall1".
About the tool mentionned by Geo, it's very useful for big scenes (I rename sometimes more than 100 objects with it at the same time). Just be careful on the box you tick
