Indeed I was able to reproduce your issue and I've created a ticket:

Please either wait until the issue gets fixed or add the items of that playlist manually.

Alternatively, if small playlists always work here is a possible workaround:
Create multiple playlists on your own and add all items of that big playlists to them.
Then add your playlists to JD (make sure they're public in that moment)!
