Export map will not export as vectors (EPS, SVG, or PDF)

[Janus]

I can't believe I'm having trouble with something so simple, but my maps will not export as vectors, no matter the settings I try.

I am using simple shapefiles and have tried "export map" as EPS, SVG, and PDF file types with "output as image" unchecked. When I open the files in Illustrator, there is only one layer: an image layer. 

I have only one layer turned on in ArcGIS, and there is no transparency. 

This is the same simple problem occurring in other posts like this, which has not been answered. https://community.esri.com/t5/3d-mapping-questions/scene-exporting-to-image-instead-of-vectors-in-sv...

Any suggestions?

Still no resolution. It must be a bug. The software is useless for me if I can't export vectors. I can't even download older versions of ArcGIS, only 3.2.0, because of how Esri controls organizational downloads.
