Filtering a list doesn't change RSS feed content

Hi,

I have a list with all shows where I wait for new content. There are two types of items in it:

  1. Shows: Wait till it reached status “ended” or “canceled”. Now show can be watched as a whole.
  2. Seasons: Wait till it has a play buttons, means it can be watched now, watch ASAP

I thought I can create at least a RSS feed for scenario two, but the RSS feed always contains all items. The filter “Display: season” doesn’t work to list only seasons, nor the JustWatch filter works to list only watchable things.
