Here are the answers at your questions, but before I wanted to say that CC is the only app in my phone to show this path (/mnt/media_rw/4D96-1407/) for my SD card. Rocket Player, X-plore, Acrobat Reader have "/storage/4D96-1407/" and I can open a book with MoonReader or Acrobat from within X-plore without trouble.

Answers:
I'm using the last version of CC: 5.1.0.3 (320)

My version of Android is Marsmallow ROM, 6.0.1 (http://forum.xda-developers.com/moto...f-6-0-t3284309)
with this Kernel: http://forum.xda-developers.com/moto...4-108-t3169304

With a MM ROM, I wanted to say a Marshmallow ROM...sorry.

That is Android 23, so CC is using the Android SAF (Storage Access Framework). When you go to CC's Folders and Formats, CC asks Android to open a dialog to select the folder and to give CC permissions to read/write that folder. CC has no control over that dialog. In other words, CC is not choosing that path, Android is. I do not know where Android gets that path, but it is probably in a configuration file somewhere.

The filemanager i'm using (X-plore) show me the path:"/storage/4D96-1407/"

Does the path /mnt/media_rw/4D96-1407/ exist? Also, unless you have rooted the device the file manager must also use the SAF, so it should get the same folder. If it does not, and apparently it does not, then there must be something in the OS that needs configuring.

When I want to change the folder in the CC settings, it's posible but with its strange path. I can tell CC to use the folder I want, it's just that for CC this folder's name is: /mnt/media_rw/4D96-1407/Books and for the others apps it's: /storage/4D96-1407/Books. CC can write the book on the folder, connect with the PC and everything but it will not send a book to a reader app.

Actually, it *is* sending the path to the reader app. My guess is that Moon+ does not have permissions to read that path, which means that the Android installation is broken in some way.

I send you the CC debug log, it has only one book for test purpose.

I never received the debug log. Did you actually send it? [EDIT]The debug log has appeared as an attachment!
