Export selection to PDF does not keep columns

Hi everyone,

I have this small question about the export pdf and columns.
When I export the full PDF, everything works fine, but whenever I just create the export of a selection, then columns in sections do not appear, which is quite annoying…
I’m running 6.2.3.2 64 bits on Windows 10.

This issue might seem linked to How to keep columns after PDF export? but did not concern the exact same problem, hence me creating a post.
