Media libraries without title display

[lukass2000]

I use Jellyfin on my Synology NAS and installed Jellifin with the SynoCommunity App.
So i do not know, how i can use this tool

Right at the beginning, when I was testing, I inserted my own images.
That must be the problem.
But if I create now a new library, it doesn't also have no title?
Is that normal?

So once you insert an image manually, you will never have a title in any library again?

Thanks?
