What cad software did you use to create this STL file?  Usually when cura fills in a void it is because the normals are backwards which is impossible in most CAD software but very easy to do in blender or sketchup.  Did you use blender or sketchup?  If so google about your cad software and the word "normals" to understand them better.

 

I'm going to be now, otherwise I'd look over your STL.

 

Hopefully someone else will look over your STL later.

 

Oh - there are many other solutions as well - there is a plugin in cura that fixes meshes - you click on the marketplace button I think and it's one of the choices, restart cura and load your stl, right click and you can analyze it and also sometimes it will fix the normals to your liking.  Plus other free model repair services out there.

You have the "Make Overhang Printable" setting enabled. This effectively fills in the area below overhangs.
