PR: Ifc Export includes elements from a different model

[thumDer]

Problem Description

I have two models open in my Revit session. One of them has steel elements, the other one has 3 floor instances. I export Ifc from the second model (single floor), Projects to Export has only this model checked. The exported ifc includes the steel elements from the other, completely different model.
