There was a bug introduced recently where entities with drop-down menus are showing the numeric values instead of the labels. I will likely release a fix for this later today.
Wall Worm 1.9873 fixes this problem. You must reparse your FGD in the global WW settings.
Also, in order to update faulty (existing entities in a scene) load Anvil and type in this in the MAXScript listener:
wallworm_update_all_entities()
That function will update entities already placed in the scene to the latest entity definitions.
