Strange behavior when creating packages with Linux

Hello,

I just started using IntelliJ IDEA on Linux, and I encountered a strange issue : when I create a package inside a package it renames the actual package like this "selectedPackage.packageNameEntered".

I use the version : 145.1617

Example :

Here is the situation :

I create a new package ("model") inside "ch.makery.address" :

Now it looks like this and I do not have a subfolder.

Do you know how to fix that ?

Thank you
