Cannot extract zip file with Ubuntu 18.04 file manager UI

[p-]

Ok, I'll admit this is a strange one... 😉

My build uses the upload-artifact action that creates a zip.
I am able to unzip that file with the macOS Finder and the Ubuntu 19.04 file manager UI.

However, if I try to extract the same zip file with the Ubuntu 18.04.2 LTS file manager (Nautilus) it fails:

The message reads: "There was an error extracting "socket-connect-bpf.zip". "Error opening file "{file}": Not a directory"
If I unzip the same file with:

unzip socket-connect-bpf.zip

it works as well...

I could reproduce this behavior on a second Ubuntu 18.04.2 install.

I don't know if the upload-artifact action could zip the files differently?
