Fixed, all entries were in the database, it just wasn't displaying because you used the same name several times (I deleted your repeat entries which fixed the issue). I think this is actually a Godot feature with item lists only displaying the greatest value (worst time) of an item type.
I'm going to make a sequel game with a different database service anyway so I don't know if I'll fix this version, but I'll definitely fix it in the next game. :)
