What items does trakt_watchlist support? Missing items in generated "Watchlist" from trakt

[gitttt54]

Hello,

I have added the following items to my Trakt.tv Watchlist:
-a full series (example)
-a season only (example)
-an episode only (example)

Now, when I start the script, it only adds the full series to the generated watchlist collection.

Is this intended behaviour?

I would expect to have all items included in the plex collection. Not only the full series.
(I add unwatched seasons or unwatched/interesting eposodes to my trakt.tv watchlist. Thats why I expect those "loose" items to show up too)

My (shamelessly copied) config:

collections:
  Watchlist TV:
    trakt_watchlist:
      - me
    sort_title: ++3Watchlist
    smart_label: release.desc
    sync_mode: sync
    label: admin
    visible_home: true
    visible_shared: false
    visible_library: false
    url_poster: https://i.imgur.com/wzk0Z14.png

Maybe I missed something to define in my config?

Well plex doesn't allow collections of different types and collections default to show collections

Thank you, I was hoping, collections would have the same flexibillity as playlists.
