.NET API OriginalFileName changes when editing a file

Hello,

I've been trying different ways to solve my problem but nothing seems to work !

Here is my problem : 
I'm trying to edit a file using the Section.PutToContentRelationForSectionAsync() method. Everything works fine and I'm actually able to change the content of my document by giving it a "Stream" object.
My issue is that the name of the file changes by a random string like "003aE6-....". Thing is I want it to stay the same name as it was when I uploaded the document. It does not cause any problem until you try to modify manually the file ! If you right click and "modify", the name of the file will be the random string ! Same if you export it to work locally on you computer !
Is there anyone who knows how to deal with this OriginalFileName issue when modifying the content of a document?

Thank you !

Best regards,
L.
