Description
### Problem Description
When I export my file to ifc with IfcSpatialParameter, it does not work for all ceilings. Just one ceiling get correct value but others are getting original level name and they are placed in that storey. If I isolate all ceilings and export, then it exports correctly. That is a very weird behaviour.

Contributor guide
Research direction
Start by reproducing the export with the attached Projekt2.zip in Revit 2024 using IfcSpatialParameter, comparing all ceilings with an isolated-ceilings export. Trace the handling of IfcSpatialContainer during IFC export and identify why only one ceiling receives the correct value. Done means all affected ceilings are assigned to the intended storey consistently.
