Cannot redeclare Module

[cbadoud]

Hi, when I try to insert this module in a content element in an article already containing a reader module, I've got this error under Contao 3.1.4:
Fatal error: Cannot redeclare class Psi\News4ward\Module\Module in ...\system\modules\news4ward\Module\Module.php on line 231
Why is it impossible to have these 2 modules working together in the same article?

I cant reproduce your error.
But it makes no sense having two News4ward Readers on the same page, the Item get found through the alias in the URL where you cant have two different.

Probably you could send me your installation?

I wanted to have a reader, and under it, related news. Doesn't it make sense? Is there another way to do that?
For the moment, I can't send you my installation, but I can make it this week-end if it's necessary.
