Is this a schedule bug?

[Anonymous]

Hello

I have a schedule that behaves very strange. I want to list the different skin areas but as you can see in the attached picture Archicad (21) does not merge uniform items as it should. ( I don´t have two building materials with the same name and I have unchecked the End Surface: Overide... Has anyone experienced something similar?

Maybe the thickness is off by 0,01 or less mm? Are there any other parameters you are scheduling that could be different?

They belong to the same wall composite structure, so all the parameters are the same

When deciding what is a uniform element, every scheduled data of and element is considered.
Since the Skin Areas are not exactly the same, they will not be merged into a single Schedule Cell.
