Wall tag changing when changing IFC version from 4 to 2x3

[Christiaan]

1. Open attached file.
2. Edit the wall style and go to the Data tab.
3. Note that the 'Mark' = "W10a"
4. Click on IFC... and change IFC version from 4 to 2x3
5. Accept IfcWallStandardCase and click on OK.

 

Behaviour experienced: Wall 'Mark' changes from 'W10a' to 'W2'

Behaviour expected: Wall 'Mark' to remain as 'W10a'

 

Does anybody know what's going on here and how to avoid it? I've messed around with the IFC version in this file in the past so the wall may well have been 'W2' originally, perhaps when it was set to IFC 2x3.

 

Edit: It doesn't resolve the problem but I received a little feedback from an engineer on that IFC button: "This button (IFC...) in Edit Style dialogs for walls/slabs/roofs is obsolete and will be removed - so, please do not use it. If you need to change something (version or data) - please, use Data Manager."
