Unable to select curtain wall on elevation view

[ReignBough]

When a curtain wall is placed below storey 0, it cannot be selected. I put two curtain wall, one on storey 0 and the other on storey -1. I then put an elevation marker in front of them. I viewed the elevation marker then select all curtain wall. Only the curtain wall on storey 0 is selected.

This is both on elevation marker and section marker. ArchiCAD 19.

Works for me just fine.
Are you still on build 3003? You could try upgrading to the latest build, many small errors were fixed in the hotfixes.
