The 3D SRID needs to be 4327, not 4326.
4326 13349 Point:0,Edge:2,Ring:1, TRUE 4327 TRUE TRUE
To update the 3D SRID's:
UPDATE export_table a SET a.bestgeometry.sdo_srid = 4327;
The 2d srid was intentional. We only have a requirement to store the z value and not use it in any calculations so I wanted to keep the spatial index in a 2d srid and only store the z value. This way we can avoid having to cast down to 2d when doing our spatial functions.
I see. Then set the flag10g to TRUE and it won't show them as faulty.
Thanks Bryan. I made the change and validation is working as expected.
