Columns Dropped on Export.

[ack_ack_ack_ack]

I'm attempting to export a joined table so the join isn't in memory.  I am required to do this because in-memory joins are not supported by the web-based "Stories" app/thing.

The first screenshot shows the point column station_point.  It draws points on a map as expected.

Any attempts to export/convert the data results in the station_id and station_point column being deleted.  As shown below. 

I need the point drawn on the map. Instead, I'm left with metadata attached to nothing.
There's no error.  The data is useless without the station_point column.  I can live without the station_id column.  No idea where it went, though.
