Prusa Slicer adds volume where a hole has to be (possible bug)

Hello,
(Sorry if this is not a right place for this issue. I'm novice here.)

I have a simple model with inner hexagonal hole for a nut. 

This is how a model looks like

And this is how it's sliced
 

You can see slightly different colour in the hexagonal hole where is the unwanted surface (volume) afters slicing. Its because there a little collar locking a nut in position.

Prusa Slicer v. 2.3.3 (win64)

STL + 3MF files temporarily available on http://leteckaposta.cz/939562432

It's bug, or am I doing something wrong?

I wanted to look at your files, but give up, trying to download.

Please Zip the files (3mf + STL) and attach them directly to the forum (upload).

Have a look at my designs on PrusaPrinters ;)...

Oh, the ZIP does the trick! ( tried to upload files directly here, but they was rejected due filetype restrictions).

Your object contains two duplicate vertices. Load STL in Blender, remove the duplicates and save STL -after that object will be sliced as expected.

As @bogdanh points out, your STL model is not manifold and have extra geometry. It may look right when shown in PrusaSlicer, but fails when sliced.
Here in Blender, showing some of the extra non-manifold edges in orange:

Using the 3D Toolbox in Blender it can be fixed. I have attached updated project file.

Thanks for your insight! It's forgotten surface body used as a tool during modelling.

Leson taken. Dissable all surface bodies before STL export.
