Fix / Update the Sort By - Date Added option

[mylinuxguy]

On collections ( and probably TV Shows )  you have a
Sort By -> Date Added 
option.  

I can't really figure out how it works... it does NOT work like expected. 

If I do a Sort By -> Date Added, Sort Order -> Descending, Filter Unplayed I get ( see attached image - sorry for the blurry pic... think it gets the point across... ) 



The latest shows I've added and not watched are: 

• SurrealEstate/SurrealEstate.S03E04.1080p.x265.mkv
  
• The.Equalizer/The.Equalizer.S05E17.1080p.x265.mkv
  
• The.Last.Of.Us/The.Last.Of.Us.S02E01.1080p.x265.mkv
  
• The.Last.Of.Us/The.Last.Of.Us.S02E03.1080p.x265.mkv
  
• Tracker/Tracker.2024.S02E18.1080p.x265.mkv
  

 I haven't added 1923 in 2 months... no way should it be showed so prominently.  The last resort was added 6 weeks ago.  

If I am sorting by Unplayed, date added descending I expect and want to see 
Tracker
The Last Of Us
The Equalizer
SurrelEstate
as the first 4 things shown here. 


there should be lots of stuff shown before 1923,  Last Resort, The Way Home, etc. those are all 6+ weeks old. 

What exactly is 'Date Added' supposed to be using for 'Unplayed content?
