Revit to IFC classification question

[semi]

Hi, 

I don't know if this is the correct forum for this question but here goes:

When exporting to IFC, some of my information of some geometry is correct, but other geometry with the same export settings aren't.

See this example:

Selecting a beam in Solibri software from an exported revit IFC shows me this:

I can perfectly see my Classification settings, the reference code and the description.

But selecting and other beam of the same category shows me this:

Steel columns also wrong:

Floors are all ok:

I don't get the logic behind this. If it were all wrong I would suggest it's a configuration error, but some data goes out perfectly so I have no idea what's wrong.

The revit settings are always the same:

Any tips guys?

I think you have only one problem Column and other beams do not show the classification name. I would suggest just reassigning the column and other beam classification/assembly codes and checking the export once again. Let me know your thoughts and further input to Assist you.

Thank You,
