Movies folder not showing up, not sure if permission issue

[EliteAlien]

Hi all. I need help. I've browsed the subreddit, this forum and Google for an answer, chmod'ed my folders, chown'ed my folders, edited everything I could think of/find online help in terms of permissions and I still can't see my Movies folder.
My server is on CasaOS, inside Debian 12. Everything is up to date.
I've loaded a few images to Imgur to help aid you in understanding my predicament: https://imgur.com/a/VlLhWXv. But first, please read on.

Here's the thing: my server used to be on Windows and my Movies and TV Shows folders are still on NTFS HDs, because I had no way of formatting the HDs without losing everything (which I didn't want to do).
I installed Debian 12 and CasaOS with no issues. I have several other "apps" running on CasaOS that can read these same folders, including Plex. But for some reason JF insists on not reading the contents of my "Movies" folder (which is in a dedicated HD named "Filmes 8TB").
These folders' mount points are /media/myuser/Filmes 8TB/Movies and /media/myuser/Séries 8TB/TV Shows.
Everything works fine while adding the TV Shows folder, but for some reason the Movies folder doesn't show anything inside it.
In Imgur you'll find my volumes configs, a sample of my movies' folder permissions and the permissions for my volumes, as well as three JF screenshots for adding my TV Shows folder and my Movies folder.

One other piece of information: this is my second install of Jellyfin. The first one was working fine until I realized that it wasn't scanning recently added movies. I then searched for a solution for this and found out that the best option was to remove my Movies library and add a new one. This is when this problem appeared.

Please, please help... I don't know what to do anymore...

This sound like a permission issue to me. Either due to the lack of the Jellyfin group or user being assigned or Docker related due to not giving Docker access to the proper media folder.
- Can you list out the actual commands for the chmod and chown.
My suggestions: sudo chown jellyfin:jellyfin -R /media/media-folder and then put other user accounts in the jellyfin group. Which gains you access to those folders from the other users. However, all the files will be recursively changed and owned by the Jellyfin user account.
- When you go in a terminal and "ls -l /media/media-folder" what is the full output.
Example of what my mounted location for movies looks like: https://imgur.com/a/yDCgqjR

- If Jellyfin in hosted in the CasaOS with a Docker container, what docker container did you use and can we see the yaml and/or how you setup the command.
