SOLVED: Sequence in music-collection off

[Hurban]

Hi – I have a problem: the sequence of the tracks shuffles when put into Jellyfin. I have tried to change the file name, tracks and other parameters starting with 01.,02.,03....etc. but still there is this reordering that does not seem completely random, but still produces a big problem as the tracks are lectures to be listened to in the proper sequence. Does anyone have a solution?
