Spotify Pack 100 tracks limit?

Hi, I am trying the Spotify Pack to list all tracks in my playlists, but when I use the limit with 1000 items and I manually sync, it says: “Last sync failed”. When I try with 100 tracks, it’s working but it doesn’t show all the tracks and covers only 2 playlists. I am using Spotify Premium.

Is importing more than 100 track possible? And if not, why do we have the options to chose 1000 or 10 000 tracks?
