Schedule issue with equipments

[graava]

I've just noticed that in Archicad 28 there's no 2D plan preview for the 'Equipment' element type in schedules. Neither 3D axonometry or other type of previews. Is this some kind of bug? I don't remember having this same issue in previous versions. 

Here is a screenshot of my schedule. The object types appear correctly but there's no preview for the equipment. The same issue continues in other schedules with objects/equipments.
